The Houston Astros received a big boost from new recruit Trey Mancini as he blasted a pair of home runs, punctuated by a grand slam, in his side's 9-3 away win against the Cleveland Guardians on Friday.

Mancini, who was acquired from the Baltimore Orioles this past week, has now hit a home run in each of his two starts for his new club. In doing so, he became the first player in the modern era to hit a home run in his first two starts for his first two teams, after also accomplishing the feat back when he began with the O's.

He struck first in the second inning, tying the game at 1-1 after Amed Rosario hit his own home run to begin the game for the Guardians, and Mancini's second home run of the game came with bases loaded in the third frame for the first grand slam of his career.

Arguably the best hitter in baseball this season Yordan Alvarez went two-for-five and notched his 73rd RBI for the season – the seventh most in the league – and his future Hall-of-Fame teammate Jose Altuve tallied one RBI from his three hits.

On the mound, Framber Valdez secured his 18th consecutive 'quality start' – defined by a pitcher going at least six innings while conceding three or fewer runs – finishing with three earned runs from seven hits and three walks in his six-and-a-third innings.

He now leads the league with 19 quality starts, and his streak of 18 consecutive is the longest since Jacob deGrom rattled off 26 in a row beginning in May 2018.

The win moves the Astros' record to 70-38 – one game behind the New York Yankees for the best record in the American League.

Yankees, Holmes blow late lead 

The New York Yankees led nearly the entire game before eventually falling 4-3 to the St Louis Cardinals, courtesy of a blown save from All-Star reliever Clay Holmes.

Josh Donaldson drove in a pair of runs for the Yankees, while AL MVP favourite Aaron Judge collected two hits and came home to score twice, giving their side a 3-2 lead heading into the eighth inning.

Determined to take no risks, the Yankees brought in Holmes an inning early to try and get to the ninth inning with their lead still in tact, but it was not to be as Holmes conceded a walk and two hits, the second being a two-run double from Paul deJong to steal the lead.

Cardinals closer Ryan Helsley made no such mistakes, closing the door and collecting the save.

Gibson produces near-perfect start for the Phillies

Philadelphia Phillies starting pitcher Kyle Gibson had a perfect game through six innings in his side's 7-2 win against the Washington Nationals.

Gibson retired the first 18 batters he faced, striking out three as he relied on strong fielding behind him to accumulate quick outs. His bid for a perfect game was eventually broken up by a hit-by-pitch to begin the seventh frame, and a single from the next batter ended the no-hitter.

He finished with one earned run from two hits and one walk in eight complete innings, while Kyle Schwarber hit his 34th home run of the season to help on the offensive side of the ball. Only Judge has more home runs this season than Schwarber.

Juan Soto scored on his San Diego Padres debut to rapturous applause as his new side won 9-1 over the Colorado Rockies on Wednesday.

Reigning Home Run Derby winner Soto, who sealed a Deadline Day trade from the Washington Nationals on Tuesday, was given a raucous applause upon his first at-bat by the Petco Park faithful.

Soto's first at-bat ended with a four-pitch walk, before hitting home plate when Jake Cronenworth was walked after being struck by Chad Kuhl's pitch.

However it was another new addition, Brandon Drury, who stole the show with a first-inning grand slam to open up a 5-0 lead with his 21st home run of the season.

Manny Machado and Cronenworth both hit home runs in the fifth inning, while Soto finished with two walks from his two at-bats, with the one run.

Cole aced by Mariners and Castillo

Gerrit Cole allowed six runs in the first inning as his poor form since the All-Star Game continued in the New York Yankees' 7-3 loss to the Seattle Mariners on Wednesday.

Cole was on the mound for the first inning, with blasts from Eugenio Suarez, Carlos Santana and Jarred Kelenic opening up a 6-0 lead. The last time Seattle hit three homers in the first inning of a game was in May 2002.

The six runs were the most allowed in any inning of the career of Cole, who became the second pitcher in the modern era to allow three homers in the first inning of a game multiple times in the same season. He has given up five or more earned runs in consecutive outings for the first time since 2017 and has an ERA of 7.00 in three starts since the All-Star Game, having gone at 3.02 prior to that.

Luis Castillo, in his first start for the Mariners, put on a clinic with eight strikeouts, allowing five hits across six-and-two-third innings.

Vogelbach grand slam in Mets triumph

Daniel Vogelbach hit a grand slam as the New York Mets knocked off the Washington Nationals 9-5 to improve their record to 66-38.

Pete Alonso blasted his 28th home run of the season in the second inning, which was also the 21st of his career against the Nats, which is the most of any opponent he has faced.

Vogelbach's moment came in the fifth inning with the Mets 2-0 up and bases loaded, hitting high deep down the right field line.

The Seattle Mariners rode a hot start to a strong 8-6 win on the road against the New York Yankees, despite missing rookie All-Star Julio Rodriguez.

With their 21-year-old superstar out of the lineup temporarily as he battles through a minor injury, Adam Frazier did a good impression in the lead-off spot, collecting two hits and two walks from his five plate appearances.

Early on, it was Eugenio Suarez coming through as he blasted a 432-foot, two-run homer in the opening frame, and Cal Raleigh made it 3-0 with his own solo shot an inning later.

A Carlos Santana sacrifice-fly made it 4-0 before the Yankees started to fight back, with Josh Donaldson's RBI double and Jose Trevino's two-run shot over the left-field wall trimming the margin to 4-3 in the fourth inning.

Santana drove in his second and third runs of the day with a clutch double in the fifth frame, but a pair of sixth-inning home runs to Yankees Donaldson and Anthony Rizzo had things tied at 6-6.

As was the theme on the day, every time the Yankees tried to make it a game again, the Mariners had the answers, again jumping straight back out in front through Sam Haggerty's pinch-hit home run in the seventh.

Frazier finished off the scoring with an RBI single in the top of the ninth, giving Mariners closer Andres Munoz an extra run of breathing room, and he finished off the save despite allowing a hit and two walks to load the bases.

Pirates win after a three-run Cruz missile

The Pittsburgh Pirates pulled off an upset win against Milwaukee Brewers ace Corbin Burnes, with rookie Oneil Cruz delivering the decisive blow.

After the Brewers hit three consecutive home runs in the sixth inning – courtesy of Willy Adames (355 feet), Rowdy Tellez (412 feet) and Kolten Wong (394 feet) – Cruz brought things back to square with his own three-run, 408-foot home run to get Burnes pulled from the game.

The Pirates ended up piling on another two runs in the bottom of the sixth inning, with Wil Crowe coming in to strike out the side for the save.

Jacob deGrom returns in Mets loss

Arguably the best pitcher in all of baseball returned to action on Tuesday as Jacob deGrom started on the mound in the New York Mets' 5-1 loss to the Washington Nationals.

In his first start of the season after a series of injuries, deGrom looked like his devastating self, striking out four of the first six batters he faced, and going on to finish with figures of one earned run from three hits and no walks in five innings, striking out six.

As soon as deGrom was withdrawn from the game, the floodgates opened for the Nationals, connecting on three home runs across the next two innings to pull away for the win.

The Minnesota Twins signalled their win-now mindset with a trio of pitching moves, while the Los Angeles Dodgers took on a big-name reclamation project on Tuesday's MLB trade deadline day.

Minnesota lead their division by one game from the Cleveland Guardians, so the decision to push their chips into the middle and make a run at the playoffs is one that makes sense, and to make any noise, they needed pitching reinforcements.

A strong hitting side, the Twins are sixth in the majors in both on-base percentage (.321) and slugging percentage (.419) – but sit in the bottom half of the league in key pitching stats ERA (19th, giving up 4.03 runs per nine innings), strikeouts (21st) and walks allowed (19th).

Out of all 30 teams in the majors, only the Washington Nationals have had fewer 'quality starts' than the Twins – defined by the starting pitcher conceding three or fewer runs in six complete innings. The Nationals are also the only team to have less 'saves' collected by closing pitchers than the Twins.

In a bid to remedy both of those issues, the Twins acquired starting pitcher Tyler Mahle from the Cincinnati Reds, and All-Star closing pitcher Jorge Lopez from the Baltimore Orioles.

The nature of a starting pitcher is that they will throw more innings, and accumulate more overall value, but Lopez is arguably the more significant addition.

One of the best closers in all of baseball this season, 29-year-old Lopez boasts a terrific 1.68 ERA and is 10th in the league in saves with 19. He has allowed 47 total baserunners in 48 innings of work for an impressive WHIP (walks and hits per innings pitched) of 0.97.

Mahle, 27, does not have spectacular numbers this season (4.40 ERA), but that was mainly due to a rocky start.

He has since rebounded with a run of nine starts of at least five innings pitched with no more than four runs conceded, including back-to-back showings against the Arizona Diamondbacks where he totalled 22 strikeouts and one earned run from 15 innings.

Completing their haul, the Twins also traded pitching prospect Sawyer Gipson-Long for established reliever Michael Fulmer from the Detroit Tigers in another win-now move.

Meanwhile, the Dodgers acquired Joey Gallo from the New York Yankees in the midst of the power-hitting outfielder's worst season of his career.

Gallo, who has a pair of 40 home run seasons on his resume, and is still only 28 years old, has been a disaster since being traded to the Yankees last season, batting .159 with just 37 hits compared to 106 strikeouts.

One of the best teams in baseball, the Dodgers are hoping a change of scenery is all that is needed to re-energise the hard-hitting lefty, and they were able to acquire him as a depth piece for only minor league pitcher Clayton Beeter, who did not figure to contribute in any way to the major league side this eason.

League leader Aaron Judge continued his remarkable form after the All-Star Game with his 43rd home run of the season as the New York Yankees flexed with a 7-2 win over the Seattle Mariners on Monday.

Judge made majors history with his 10th home run since the All-Star Game, joining Albert Belle in achieving that feat in only 12 games after the break.

The Yankees outfielder had hit a first-inning double, before Anthony Rizzo's three-run blast – his 26th home run of the season – opened up an early 3-0 lead.

Judge took center stage in the second inning with his home run putting the Yankees up 5-1, marking 12 blasts in his past 14 games.

Jose Trevino got in on the act, after a lean month, with home runs in the fourth and eighth innings for his first career multi-homer game.

The result keeps the Yankees top of the American League (AL) East with a 70-34 record, while the Mariners are second in the AL West with a 55-49 record.

Judge leads the majors for home runs this season with 43 with a league-high .680 slugging percentage, batting at .299 with 89 runs, 115 hits and 93 RBIs.

Hot property Soto stars as Mets see off Nats

Amid trade speculation, Juan Soto underlined his value with the Washington Nationals with a fine all-round performance in their 7-3 loss to the New York Mets.

Soto showed off his speed around the bases to score for 1-0 in the first inning, before some brilliance from the outfield saw him throw out runner Tomas Nido on the home plate.

After Pete Alonso's 27th blast of the season put the Mets 4-1 up, Soto returned fire with his own home run in the fourth inning, his 21st of the year.

Francisco Lindor's sixth inning homer rounded out the win for the Mets who improve to 65-37.

Dodgers too strong for Giants

Max Muncy and Trea Turner both homered as the Los Angeles Dodgers proved too good for National League (NL) West rivals San Francisco Giants 8-2.

Muncy's second-inning two-run blast put the Dodgers ahead after Darin Ruf scored in the first, with Freddie Freeman driving in Mookie Betts in the fourth to open up a 4-1 lead.

Turner unleashed his 17th home run of the season at the top of the seventh inning with a fly ball to center field to settle the contest, helping the Dodgers move to 69-33 at the top of the NL West.

The San Diego Padres have made a key addition after trading in All-Star closer Josh Hader from the Milwaukee Brewers ahead of Tuesday's MLB Trade Deadline.

The addition of 28-year-old left-hander Hader is a major boost for the Padres, who have struggled in late-inning situations this season.

Hader is the 2022 league leader in saves, with 29 from 31 save opportunities this season, although he has career-worst 4.24 ERA which dipped to 12 during July.

The deal sees left-handed reliever Taylor Rogers, left-handed pitching prospect Robert Gasser, right-hander Dinelson Lamet and outfielder Esteury Ruiz sent to the Brewers.

"Josh Hader is one of the best closers in the league," Padres general manager A.J. Preller said.

"He's been there, done that, pitched in big spots, big playoff games. He's got elite stuff."

Hader, who has been with the Brewers since 2017, joins the Padres who have a 57-46 record to sit second in the National League West this season.

"Thank you for the support throughout my career," Hader wrote on Instagram. "Y'all have been great to me. The people, the energy, the love! There will always be a special place in my heart for MKE."

In other moves, the New York Yankees added right-handed starting pitcher Frankie Montas and closer Lou Trivino from the Oakland Athletics, along with reliever Scott Effross from the Chicago Cubs.

The Yankees, who have a 69-34 record, had previously brought in All-Star outfielder Andrew Benintendi from the Kansas City Royals.

The Houston Astros acquired first baseman Trey Mancini from the Baltimore Orioles along with catcher Christian Vazquez from the Boston Red Sox.

According to reports, outfielder Tommy Pham is set to join the Red Sox from the Cincinnati Reds.

The New York Yankees made a move to bolster their already strong bullpen on Monday by acquiring right-hander Scott Effross from the Chicago Cubs for minor league pitcher Hayden Wesneski.

Effross made his major league debut for the Cubs last August and had a 3.68 earned run average (ERA) over 14 2/3 innings in 2021.

He has been solid this season, posting a 2.66 ERA with 50 strikeouts and just 11 walks in 44 innings over 47 appearances.

New York entered Monday's action with the best record in the AL at 69-34, and their 2.92 bullpen ERA ranks second in the majors behind the Houston Astros (2.79).

The Yankees, though, recently lost right-hander Michael King (6-3, 2.29 ERA, 66 strikeouts in 51 innings) to a season-ending elbow injury and were looking to upgrade their relief corps ahead of Tuesday's MLB trade deadline.

Wesneski was a sixth-round selection by the Yankees in the 2019 Amateur Draft. The right-hander has gone 6-7 with a 3.51 ERA in 19 starts this season at Triple-A Scranton/Wilkes-Barre.

The Kansas City Royals avoided a series sweep on Sunday with a 8-6 come-from-behind win on the road against the New York Yankees, with a pair of late home runs turning the tide.

Both starting pitchers finished with mediocre figures, but they were both spotless early, holding the game scoreless through the first four innings. The fifth inning was a different story, with the sides combining for seven runs. 

The Royals struck first as Nick Pratto came through with a two-run, bases loaded single, before Maikel Garcia followed him with an RBI double, and they capped off a four-run frame with an RBI groundout from Whit Merrifield.

But the best team in baseball this season answered right back, with Kyle Higashioka batting in a run with his single, before D.J. LeMahieu brought him home with a homer to the short porch at right-field. 

Later in the seventh inning, with Aaron Judge and Aaron Hicks on base, Anthony Rizzo shot the Yankees into a 6-4 lead with the longest hit in the game up to that point, a 418-foot home run over the right-field wall.

Kansas City's Hunter Dozier topped that the next inning with a 420-foot shot to left-field, trimming the margin to 6-5 and setting up an exciting finish.

Needing three outs to secure the win, the Yankees brought in elite relief pitcher Clay Holmes for the save, but it did not go to plan.

Holmes got the first out, but then issued a five-pitch walk to Merrifield, before hitting Bobby Witt Jr with a pitch to put runners on first and second with Salvador Perez at the plate.

Perez had been swinging a hot bat as of late with three home runs in his past seven games, and he added one more with a monstrous 441-foot nuke to center-field, jumping ahead 8-6 in the final frame.

Instead of handing the ball to a new closer, the Royals let Taylor Clarke head back out for his second inning to finish the job.

Yankees superstar Aaron Judge finished hit-less, but he contributed with two walks and a run.

The win is only the Royals' second from their past 12 meetings with the Yankees.

Austin Riley walks it off for the Braves

A quality pitching duel broke out in the Atlanta Braves' 1-0 win against the Arizona Diamondbacks, with Austin Riley batting home the first run of the game in the bottom of the ninth inning.

Braves ace pitcher Max Fried allowed four hits and two walks with five strikeouts in his seven scoreless innings, while Arizona's Merrill Kelly was slightly better, conceding three hits and two walks to go with eight strikeouts over the same stretch of innings.

The Braves had five hits in the game, and two of them were by Riley, who has quickly established himself as a realistic NL MVP candidate. 

Riley is fourth in the league in home runs (29), and second in total bases (239) – trailing only Aaron Judge.

Alvarez plays the hero in Houston

Speaking of players having unbelievable under-the-radar seasons, Houston Astros star Yordan Alvarez continued what is arguably the best hitting season in the majors with the winner in his side's 3-2 victory against the Seattle Mariners.

He went zero-for-four in regulation, but with scores tied in extra innings he came through with a clutch hit to drive in the winning run.

Alvarez leads the league in on-base percentage (.417) and trails only Judge in slugging percentage (.670 compared to Judge's .671).

Aaron Judge became the second-fastest player to ever hit 200 career home runs as he connected on his 42nd of the season in the New York Yankees' 8-2 home victory against the Kansas City Royals.

Judge's moment came in the second inning, but it was not his side's first home run of the night after D.J. LeMahieu blasted a 410-footer to center-field as the Yankees' first batter of the game.

After All-Star catcher Jose Trevino got on base, Judge took one opposite-field to put the Yankees 4-0 up. He reached his 200th home run in his 671st career game – 13 games slower than former Philadelphia Phillies slugger Ryan Howard.

That was not all Judge would do in this contest, getting on base four times as he finished with a pair of hits and a pair of walks. He now has 10 more home runs than second-placed Kyle Schwarber (32).

On the mound, Nestor Cortes put in a strong showing to be credited with the win, giving up two runs in five innings, striking out five. 

After a clean Aroldis Chapman inning in relief, Clarke Schmidt then came in for a three-inning save, striking out five batters and throwing 52 pitches.

Twins stars go deep against Padres

Both Byron Buxton and Carlos Correa hit home runs in the Minnesota Twins' 7-4 win on the road against the San Diego Padres.

Stars on both sides were swinging a heavy bat, with Padres MVP candidate Manny Machado opening the scoring with his own solo shot in the third inning.

But the Twins had all the answers, as Buxton destroyed a baseball 434 feet over the left-field wall an inning later, before Correa kick-started his side's five-run eighth frame with his own two-run homer.

Shohei puts on a show

The Los Angeles Angels rallied back late to defeat the Texas Rangers 9-7, headlined by reigning AL MVP Shohei Ohtani's 22nd home run of the season.

The superstar designated hitter – who has also pitched the sixth most strikeouts in all of baseball this season (146 in 17 starts) – connected on a 424-foot, three-run home run to center-field in the third inning to give the Angels a 3-2 lead. Only 15 players have hit more home runs this campaign.

Texas fought back in the middle innings through home runs to Marcus Semien and Meibrys Viloria, but the Angels scored five in the eighth inning to steal the result.

Aaron Judge's magical season continued on Friday night as he blasted another two home runs to help the New York Yankees defeat the Kansas City Royals 11-5 at Yankee Stadium.

New York got off to a perfect start in the first inning thanks to a 422-foot Anthony Rizzo solo homer, before Judge connected on his own monstrous 449-foot nuke in the third inning to make it 3-0.

It was smooth sailing for Yankees ace Gerrit Cole on the mound through four innings, but he struggled mightily in the fifth, giving up five runs after a three-run homer to Salvador Perez. Cole finished with five earned runs and nine strikeouts from his six innings of work.

The Royals' 5-3 lead would hold until the eighth inning, when newly acquired Andrew Benintendi trimmed the margin by one with his RBI infield single, before Aaron Hicks was gifted a bases-loaded walk to tie the game at 5-5.

Their damage in the eighth inning was far from done, with Isiah Kiner-Falefa and Jose Trevino driving in a run each, bringing Judge to the plate with bases loaded.

The American League MVP co-favourite took full advantage, crushing a grand slam to bring his RBI tally for the day up to six, putting a bow on the win.

His home runs were his 40th and 41st of the season – nine clear of second-placed Philadelphia Phillies slugger Kyle Schwarber (32).

Mets get to Alcantara

Arguably the best pitcher in all of baseball this year, Miami Marlins ace Sandy Alcantara, had his worst start of the season as his side went down 6-4 at home against the New York Mets.

The NL Cy Young award favourite was clearly off from the beginning, needing 53 pitches to get through the first two innings, allowing four hits, three walks and three runs in the process. 

With the game tied at 4-4 in the eighth inning, it was Mets lead-off hitter Brandon Nimmo who was the hero with a two-run home run, which proved to be the difference.

Alvarez stays hot for Houston

Yordan Alvarez may not have the home run total of Aaron Judge, but the Houston Astros All-Star has been statistically the best hitter in all of baseball this season, showing his talent in an 11-1 drubbing of the Seattle Mariners.

He got on-base from all five of his at-bats, finishing three-for-three at the plate with two walks, including his 30th home run of the season – third-most in the majors.

Incredibly, he leads the league in both on-base percentage (.423) and slugging percentage (.687).

The Philadelphia Phillies rode a strong starting pitching performance from Zack Wheeler to an 8-4 road victory against the Pittsburgh Pirates on Thursday.

All nine Phillies batters finished with at least one hit – racking up 15 total hits as a team – and it got started in the first inning as Darick Hall made it a 2-0 game with his two-run triple. Nick Castellanos then drove in Hall with a base hit to make it 3-0 in the opening frame.

Wheeler never gave the Pirates a chance to fight back into the contest, holding the home side scoreless until late in the seventh inning. He finished with two earned runs from three hits and three walks, striking out eight.

After Alec Bohm's base hit to make it 4-0 in the second inning, there was a lull in the action until Kyle Schwarber made his presence known in the sixth frame.

With two runners on base, Schwarber connected on his 32nd home run of the season, trailing only Aaron Judge of the New York Yankees.

The Pirates rallied hard in the last inning, scoring five runs from four hits off Jeurys Familia, but there was not much to cheer about up until that point, except for an exciting showing from rookie Cal Mitchell.

Mitchell delivered the only runs for his side in the first eight innings with his towering 414-foot, two-run homer to center-field off Wheeler. He finished three-for-four at the plate, also adding a pair of singles.

Judge does it again for the Yankees

Aaron Judge won the New York Yankees another game off his bat as he blasted the game-winning, walk-off home run to defeat the Kansas City Royals 1-0 at home.

Both sides pitched beautifully, with Royals starter Brady Singer giving up just one hit while striking out 10 in seven innings, while Yankees starter Jameson Taillon struck out eight batters in six scoreless frames.

The home run was Judge's league-leading 39th of the season – seven more than any other player.

Angels blow another Ohtani gem

The Los Angeles Angels wasted another terrific starting pitching performance from two-way All-Star Shohei Ohtani, going down 2-0 at home to the Texas Rangers.

Ohtani struck out 11 batters in six innings, giving up two runs from eight hits in his 10th quality start (meaning at least six innings pitched and three or fewer earned runs) of the season. He now has 145 strikeouts for the season – the sixth most in the majors, and the five players ahead of him have all started at least two more contests.

Only Atlanta Braves rookie Spencer Strider (13.4) has a higher strikeouts-per-nine-innings stat than Ohtani's 13.1.

The New York Yankees have acquired outfielder Andrew Benintendi from the Kansas City Royals in exchange for three minor leaguers.

New York has been looking for an outfield bat with Giancarlo Stanton going on the injured list recently and Joey Gallo continuing his season-long struggles.

Benintendi, a first-time All-Star this season, was among the better rental bats available and is a free agent after this season. He is batting .321 with three home runs and 39 RBIs in 92 games for the Royals.

The left-handed hitting Benintendi spent his first five seasons with the Boston Red Sox before he was traded to Kansas City in February 2021.

He was one of 10 players that were unable to play in Kansas City’s recent series in Toronto because he is unvaccinated. The Yankees have three games remaining in Toronto this season.

The Yankees own the best record in the majors at 66-33 but have lost 12 of their past 20 games.

Despite missing a pair of National League MVP candidates, the St Louis Cardinals rode a big performance from future Hall-of-Famer Albert Pujols to a 6-1 away win against the Toronto Blue Jays.

With both Paul Goldschmidt and Nolan Arenado unavailable for their side's trip to Toronto due to their vaccination status, it was a combination of new blood and a blast from the past as they made it look easy.

40-year-old starting pitcher Adam Wainwright was at the peak of his powers, giving up just five hits and no walks for one earned run in seven innings, striking out eight batters. 

While Wainwright controlled the contest with the ball, 42-year-old Pujols made noise with the bat, knocking a single in his first at-bat, a double in his second try, and then a massive 439-foot, three-run homer with his third trip to the plate. It was longer than any home run Pujols hit in this year's Home Run Derby.

Rookie Nolan Gorman – 20 years younger than Pujols – also went deep with a solo home run, while he and 24-year-old Lars Nootbaar were two of five Cardinals to collect multiple hits.

Blue Jays star Vladimir Guerrero Jr finished two-for-four at the plate, while ace pitcher Kevin Gausman struggled in one of his worst performances of the season. 

Gausman gave up five runs in less than five innings, allowing eight hits and a walk with his six strikeouts.

Mets walk-off against Yankees

The New York Mets threatened to waste a spectacular start from pitcher Max Scherzer, but ultimately got the job done in the bottom of the ninth inning to defeat the New York Yankees 3-2 in walk-off fashion.

Pete Alonso's solo home run in the second inning and Francisco Lindor's RBI single in the third frame were the only runs before Max Scherzer was withdrawn, having pitched seven shut-out innings.

As soon as Scherzer was removed, the Yankees came back with a two-run homer from Gleyber Torres, but Eduardo Escobar led off the ninth inning with a double, setting up Starling Marte to be the hero and drive him in with a base hit.

J-Rod does it again for the Mariners

Rookie All-Star Julio Rodriguez showed once again why he is one of the most exciting young talents in all of baseball, blasting a three-run home run to give his Seattle Mariners a 4-2 home win against the Texas Rangers.

Rodriguez, 21, stepped up to the plate in the seventh inning with two runners on base, trailing 2-1, and he connected on a 419-foot no-doubter over the left-field wall to snatch back the lead.

This season, Rodriguez leads all rookies in hits (96), runs (54), home runs (17), RBIs (53), and stolen bases (21).

Eduardo Escobar and Edwin Diaz came up big as the New York Mets beat their cross-town rival Yankees in what could be a potential World Series rehearsal on Tuesday, emerging with a 6-3 win.

Kicking off a highly anticipated Subway Series, with 2015 being the last time the two teams lead their respective divisions, the Mets made the big plays amid a charged atmosphere in Queens.

Back-to-back home runs from Anthony Rizzo and Aaron Judge put the Yankees up 2-0 in a thrilling first inning, with the Mets rallying back with four runs in their opening frame, including Escobar's huge two-run, two-out shot off Jordan Montgomery.

Before extending their lead to 6-3 in the eighth inning, Diaz came in to close for the Mets, striking out four and giving up a solitary hit for his 22nd save out of 25.

Running away with the American League at one point, the Yankees now only lead the Houston Astros by two games on 66-32, while the Mets moved to 60-37 and within five of the National League-leading Los Angeles Dodgers.

Springer slam propels Blue Jays

Though his team trail the Yankees by 11.5 games in the AL East, George Springer hit the seventh grand slam of his career, as the Toronto Blue Jays claimed a 10-3 win over the St Louis Cardinals.

The Cardinals were without Paul Goldschmidt and Nolan Arenado, whose unvaccinated status prohibits them from entering Canadian soil, with Alejandro Kirk hitting his 12th homer of the year.

It was not enough against the Blue Jays, who notched up a tie-breaking five-run sixth inning via Springer's slam and Matt Chapman's RBI single, to extend their winning streak to seven games.

Pinder punches second slam of the night in A's win

The Houston Astros were not able to capitalise on the Yankees' defeat and edge closer in the AL standings, with the Oakland Athletics earning a 5-3 win.

The best and worst records in the AL West faced off and the latter reeled off a four-run third inning to get the eventual win, with Chad Pinder slugging a grand slam of his own off Luis Garcia.

The A's are now one game away from a shock three-game series sweep against the Astros, who remain stuck on 64-34.

All-Star Giancarlo Stanton has been placed on the New York Yankees' 10-day injured list due to left Achilles tendonitis.

Yankees outfielder Stanton has been in strong form in the majors this season, batting .228 with 24 home runs and 61 RBIs. He also won last week's All-Star Game MVP.

Stanton had been out of the Yankees' starting line-up in their past two games and the franchise announced the roster move ahead of Tuesday's game against the New York Mets.

The 32-year-old had undergone an MRI on Monday after experiencing a sore Achilles, with Yankees manager Aaron Boone hoping it was a "minor thing".

Boone revealed that Stanton will take a complete break from baseball for 10 days and indicated that Stanton's timeframe to return to play was roughly two to three weeks.

"Could be shorter. We'll see," he said. "We'll just kind of make those evaluations, or the trainers [will], and see how he does this week."
