Bruins 4, Maple Leafs 1: David Krejci led the way with a goal and two assists as host Boston dominated Game 1 of its Eastern Conference first-round series with Toronto.

Defenseman Wade Redden added a goal and an assist while Nathan Horton and blue-liner Johnny Boychuk also scored for the fourth-seeded Bruins, who host the Maple Leafs in Game 2 on Saturday. Tuukka Rask made 19 saves in his first playoff start since May 14, 2010.

James van Riemsdyk opened the scoring on the power play and James Reimer stopped 36 shots in his first career playoff start for fifth-seeded Toronto, which fell to 3-11-2 in its last 16 visits to Boston.

The Bruins rebounded after van Riemsdyk drew a tripping penalty on Patrice Bergeron and put a backhand shot past Rask 1:54 into the contest. Redden blasted a loose puck in the left faceoff circle at 16:20 and Horton tipped Redden’s point shot on the doorstep with 12 seconds remaining in the period.

Krejci extended the lead midway through the second period when he spun in the slot and flipped a wrist shot around Reimer. Boychuk slapped a shot from the point that eluded Reimer 5:19 later and Rask only needed six saves in the final 20 minutes to preserve the victory.
