BOSTON — Charlie Coyle scored a pair of third-period goals, stealing the spotlight from fellow Boston University product Macklin Celebrini in his first game at the TD Garden as an NHL player and leading the Bruins to a 6-3 victory over San Jose on Monday.

It was Boston’s 14th straight victory over the Sharks.

Coyle converted a backhanded pass from Matt Poitras to make it 3-3 with about 12 minutes left in the game for his first goal since Dec. 27. He made it 4-3 four minutes later on a shot that bounced off goalie Yaroslav Askarov’s pads and into the net.

It was the second own goal for San Jose on the day: David Pastrnak’s second-period score ricocheted off Sharks defenseman Jake Walman, who was standing at the top of the crease when the Bruins forward banked the puck into the net off his skates.

Vinni Lettieri scored Boston’s first goal, and Brad Marchand and Elias Lindholm added empty netters. Jonas Korpisalo stopped 25 shots for Boston.

Lexington, Massachusetts, native and Boston College product Will Smith had a goal and an assist for the Sharks, who have not beaten the Bruins since 2016. Askarov made 27 saves as San Jose lost for the sixth time in seven games.
