David Pastrnak scored with 1:53 left in overtime, taking a pretty Mason Lohrei pass to beat Darcy Kuemper and lift the Bruins to a 2-1 victory over the Los Angeles Kings at the Garden on Saturday.

After seeing 20 goals scored in the first two games of the season, offense did come easily in the matinee.

In a scoreless first period, the Bruins had an opportunity to strike first when they drew two LA penalties in the period, but both advantages were marred by turnovers and Jeremy Swayman was called on to make at least one high danger stop on the Kings PK.

The Kings got their first power play early in the second when Nikita Zadorov boarded Tanner Jeannot. Though LA didn’t technically score on the PP, the B’s were still in scramble mode when a loose puck squirted out from the slot to Trevor Moore on the right side and he buried into an empty net at 5:22.

The Garden grumbles turned into boos when the B’s squandered another later in the second. The next time the B’s got a power play, they immediately forfeited by taking a penalty of their own. The strategy, unintentional or not, paid off.

On the 4-on-4, Brad Marchand stole the puck from Jordan Spence in the neutral zone and moved in on a 2-on-1. He fired a low shot that produced a good rebound for Elias Lindholm and, from deep in the right circle, Lindholm’s one-timer beat a sliding Kuemper to even the game at 16:50 of the second.

The third period was scoreless, though each team had power plays in the final 6:16 of regulation that went for naught.
