Casey Mittelstadt scored twice in a four-goal third period to lead the Buffalo Sabres to a 5-2 win over the Vegas Golden Knights on Friday.

Zach Benson and former Golden Knight Alex Tuch also scored in the third and Dylan Cozens had a first-period goal and added two assists to help Buffalo improve to 3-1-1 in its last five games.

Devon Levi turned aside 32 shots and is 3-0-1 with a 1.71 goals-against average since he was recalled from the AHL earlier this month.

Ivan Barbashev and Jack Eichel had goals for Vegas, which had a nine-game point streak stopped (6-1-3).

Pastrnak lifts Bruins over Islanders in shootout

David Pastrnak scored the deciding shootout goal to lift the Eastern Conference-leading Boston Bruins to a 5-4 win over the New York Islanders.

Pastrnak, Morgan Geekie, James van Reimsdyk and Mason Lohrie scored in regulation, with Lohrei netting the equaliser with 3:09 left in regulation on a bank shot from behind the goal line.

Brock Nelson, Bo Horvat, Alexander Romanov and Simon Holmstrom had goals for the Islanders, who had won four straight but moved to 6-0-2 in their last eight games.

Stars rally past Senators after Oettinger injured

Miro Heiskanen and Matt Duchene scored 44 seconds apart in the third period to rally the Dallas Stars to a 5-4 win over the Ottawa Senators after losing goalie Jake Oettinger to an early injury.

Oettinger left eight minutes into the game with a lower-body injury after allowing goals on the Senators’ first two shots on net. Scott Wedgewood entered and stopped 25 of 27 shots for the win.

Joe Pavelski, Esa Lindell and Thomas Harley also had goals for Dallas, which won its second straight.

Drake Batherson scored twice for Ottawa and Jake Chychrun had three assists in the Senators’ third consecutive loss.

Nathan MacKinnon, Mikko Rantanen and Ross Colton all had goals within a span of just over four minutes in the third period to rally the Colorado Avalanche to a 6-5 win over the Calgary Flames on Monday.

Rantanen scored with 6:29 left to play to tie the game, then earned his second assist of the night when MacKinnon recorded the eventual winning goal on a breakaway with 4:30 remaining.

Colton started Colorado's comeback by knocking in a rebound with 8:40 left that cut the Flames' lead to 5-4.

Calgary had gone ahead on late second-period goals from Connor Zary and Yegor Sharangovich, with the latter prompting Avalanche head coach Jared Bednar to replace goaltender Alexandar Georgiev after the second intermission.

Ivan Prosvetov stopped all 11 shots he faced in relief of Georgiev, who allowed five goals on 22 shots.

Former Colorado center Nazem Kadri put Calgary ahead in the first period before the Avalanche's Tomas Tatar tied it later in the frame. Colorado then took a 2-1 lead when Cale Makar scored on a power play 1:43 into the second.

Goals by Andrew Mangiapane and Blake Coleman sent the Flames back in front, but Ben Meyers scored off a feed from Andrew Cogliano with 5:03 left in the second to briefly draw the Avalanche even at 3-3.

Colorado snapped a two-game losing streak, while Calgary has now lost four of five. Dan Vladar finished with 31 saves for the Flames. 

Islanders blow late, recover to defeat Maple Leafs in overtime

Bo Horvat scored 46 seconds into overtime as the New York Islanders recovered from blowing a late lead to come through with a 4-3 win over the Toronto Maple Leafs.

Toronto rallied from a two-goal deficit to force overtime when Morgan Rielly scored with seven seconds remaining in regulation. Horvat sent a feed from Mathew Barzal past Maple Leafs goaltender Ilya Samsonov early in the extra session, however, to give New York its third consecutive win.

Rielly's goal did enable Toronto to extend its point streak to six games, a stretch in which it's gone 4-0-2. The Islanders are now 5-0-1 over their past six.

The Islanders took a 3-1 lead early in the second period on Kyle Palmieri's goal, but John Tavares scored on a redirection 7:43 into the frame to cut the Leafs' deficit to one.

Tavares, the former Islanders' captain, later recorded his 1,000th career point on Rielly's game-tying goal.

Auston Matthews' 19th goal of the season, a power-play score 5:50 into the contest, gave Toronto an early 1-0 edge before the Islanders forged ahead later in the period on goals from Brock Nelson and Casey Cizikas. 

Noah Dobson finished with three assists for New York, while Ilya Sorokin made 14 of his 37 saves in the third period and had two more in overtime.

Samsonov stopped 25 shots for Toronto.

Benn hits assist milestone as Stars down short-handed Red Wings

Miro Heiskanen had two goals and an assist to lead the way as the Dallas Stars rolled to a 6-3 victory over the depleted Detroit Red Wings. 

The Stars scored twice in all three periods, including four straight goals between the first and second, to get back on track after losing three of their four previous games. Esa Lindell and Jason Robertson each delivered a goal and an assist to support a 27-save effort from Jake Oettinger.

Jamie Benn assisted on Heiskanen's first goal, the 500th of the Dallas captain's career.

Detroit was dealt a third consecutive loss while playing without both captain Dylan Larkin and forward David Perron. Larkin is out with an upper-body injury he sustained from a cross-check by Ottawa's Mathieu Joseph in Saturday's loss to the Senators, while Perron began serving a six-game suspension for cross-checking Ottawa's Artem Zub in retaliation.

The Red Wings did take a 1-0 lead when Daniel Sprong scored 5:20 in, but goals by Heiskanen and Lindell later in the first period put Dallas ahead. Robertson and Matt Duchene then scored 2:14 apart in the second to extend the Stars' advantage to 4-1.

Jonatan Berggren quickly answered Duchene's goal to trim Detroit's deficit, and the Red Wings cut the lead to 4-3 when Joe Veleno scored on a power play with 6:39 remaining.

Joe Pavelski countered with a power-play goal 30 seconds after Veleno's strike, however, before Heiskanen sealed the win with an empty-netter inside the final minute.

James Reimer stopped 29 of 34 shots for Detroit.
