High-powered Bruins roll to Game 1 victory

Rick Nash and the Bruins’ high-scoring line of Patrice Bergeron, David Pastrnak and Brad Marchand are off to a flying start in the second round of the Stanley Cup playoffs.

Nash had two goals and Bergeron, Pastrnak and Marchand combined for 10 points Saturday, helping the Bruins pull away for a 6-2 victory over the host Lightning in Game 1 of the best-of-seven series.

Bergeron also scored twice, Marchand had a goal and two assists, and Pastrnak finished with four assists in a dominating performance.

Tuukka Rask stopped 34 shots for the Bruins, who finished one point behind the Lightning for the Atlantic Division title, as well as the No. 1 seed in the Eastern Conference.

“(Rask) was really good,” Bruins coach Bruce Cassidy said. “He gave us more than a chance to win early on when we were still trying to find our legs. We weren’t executing very well. They were better than us, and then our top guys started finishing their chances.”

Dan Girardi and Mikhail Sergachev scored for the Lightning, who trailed 3-2 entering the third period.

Marchand and Bergeron hiked the Bruins’ advantage to three goals before Jake DeBrusk added an emptynetter with 6:19 remaining.

The Bruins had just 10 shots against Lightning goalie Andrei Vasilevskiy over the last two periods, but made the most of the limited opportunities.

Game 2 is Monday night at Amalie Arena.

Rask won three of four starts against the Lightning during the regular season, with the Lightning’s lone victory coming in the final meeting.

Pastrnak assisted on each of the Bruins’ first three goals and added another on Bergeron’s third-period goal, giving him 12 helpers in eight playoff games.

“They’re good. They’ve played together for a while and they know where to find each other,” Lightning coach Jon Cooper said of the Bruins’ top line.

Nash, meanwhile, got his second and third goals of the postseason, scoring on the power play at 17:11 of the opening period and 12:33 of the second to put the Bruins up 3-1. Sergachev countered on the power play, trimming the lead to 3-2.

The Lightning actually outshot the Bruins 36-24.

Logan Couture scored on the power play at 5:13 of the second overtime — his second goal of the game — as the Sharks evened the series at 1-1 and handed the expansion Golden Knights their first postseason loss in six games.
