World Series champions Los Angeles Dodgers were humbled on the Opening Day of the new Major League Baseball season 8-5 by the Colorado Rockies on Thursday.

The Dodgers had 14 stranded runners throughout the game while Cody Bellinger hit a ball into the stands which did not count as a home run on a strange afternoon.

With crowds returning to MLB, the Dodgers were unable to get off to a flying start.

"Honestly, we just didn’t play a good baseball game," Dodgers manager Dave Roberts said. "All the way around, we didn’t play well."

In the Houston Astros' first game back playing in front of crowds since their cheating scandal emerged they were jeered and boed in an 8-1 win on the road against the Oakland Athletics.

Back-to-back home runs from Michael Brantley and Alex Bregman in the eighth put the Astros out of sight and silenced the crowd.

Trout lifts Angels, Mariners mighty comeback

Mike Trout flexed his muscle as the Los Angeles Angels rallied to beat the Chicago White Sox 4-3. At the bottom of the eighth, a visibly pumped Trout's hit gave him an RBI and tied the game. Shohei Ohtani then got on the board after an error by second baseman Nick Madrigal.

The Seattle Mariners trailed 6-1 in the eighth inning against the San Francisco Giants before mounting a remarkable fightback and eventually prevail 8-7. The winning run came when Jake Fraley walked with the bases loaded.

The New York Yankees' bats let them down as they were beaten 3-2 by the Toronto Blue Jays.

The Tampa Day Rays shut out the Miami Marlins in a 1-0 win earned by Austin Meadows' solo home run in the ninth.

Bellinger denied by mix-up

Bellinger was denied his first homer of the new season in a moment of confusion, when team-mate Justin Turner, who was on first base, thought Bellinger had been caught in the outfield and ran back. Bellinger's hit was actually fumbled by Raimel Tapia over the fence so when Turner reversed and passed by the left-hander that made him out and resulted in only an RBI single.

First homer of season

Detroit Tigers hitter Miguel Cabrera claimed the maiden homer of the new season in driving snow, which left him confused, sliding into base just in case it had not cleared the fence.

Dodgers to bounce back

The Dodgers will look to bounce back from their opening day loss on Friday on the road again versus the Colorado Rockies.

San Diego Padres star Fernando Tatis Jr. put on a show with a memorable grand slam in a Spring Training win over the Arizona Diamondbacks.

Tatis is fresh off signing a record-setting extension with the Padres last month – an eye-popping 14-year, $340million contract, which is the longest deal in MLB history and also the largest contract awarded to a player not yet eligible for arbitration.

MLB's new poster boy and the generational superstar teased what is to come in 2021 with a grand slam in the second inning of Tuesday's victory against the Diamondbacks.

Tatis sent the ball 441 feet to left field at Salt River Fields – a home run that went viral on social media.

"Hit it about as clean as you can hit a ball," Padres manager Jayce Tingler said of Tatis, who hit his first career grand slam against the Texas Rangers last season. "That was really, really good to see."

Tatis, who flipped his bat in celebration, also singled in the first inning and then stole second as Trent Grisham was allowed to sprint home.

"Had a couple good defensive plays, great at-bats, did something on the bases," Tingler said. "That's everything you want to see."

Tatis won a Silver Slugger award last season, having hit .277 with 17 home runs and 45 RBIs in the coronavirus-shortened 2020 campaign.

The powerful 22-year-old is the first player in MLB history to have at least 35 home runs and 25 stolen bases within the first 150 games of his career.

Tatis packs a punch with the bat – he led the majors in average exit velocity (95.9 mph), hard hit percentage (62.2), and balls hit 95-plus MPH (102).

He also enjoyed a remarkable rise defensively following an erratic rookie season at shortstop.

Tatis went from minus-13 outs above average (OAA) to plus-seven – his plus-20 improvement the largest of any player across that period.

When it comes to on-base plus slugging, Tatis stacks up well. Since 1920, Tatis (150.8) is only behind Juan Soto (153.9 – 2018-20), Albert Pujols (159.3 – 2001), Jimmie Foxx (160.0 – 1925-29), Ted Williams (161.5 – 1939-40) and Mike Trout (165.0 – 2011-13) for highest OPS-plus up until the age of 21.

Using the same timeframe, but for wins above replacement (WAR) among shortstops, Tatis (5.6) ranks ninth. Alex Rodriguez is top (13.6 – 1994-97).
