BOSTON (AP) ― It took the Boston Bruins just over 2 minutes to turn a scoreless tie into a 3-0 lead.

The first-period scoring outburst was more than enough offense for the Bruins in a 3-0 shutout over the slumping Philadelphia Flyers on Saturday.

Boston played one of its best defensive games of the season, limiting Philadelphia to 23 shots as Tuukka Rask picked up his 13th career shutout despite not seeing the puck during several long stretches as his teammates controlled play at the other end of the ice.

“We took their time and space away a lot of times and didn’t give them second chances,” said Chris Kelly, whose goal with 6:32 left in the first period put Boston up 2-0.

Tyler Seguin had just given the Bruins a 1-0 lead of the game when he scored on a power play with 8:07 left, his third goal in two games.

Kelly followed that with a wrist shot from the slot, then Daniel Paille finished the flurry by beating Ilya Bryzgalov on a breakaway with 5:08 still to go in the first. The goals came in a span of just 2:18 and the Bruins remained in command the rest of the way.

“I think we only had one shot in the first 10 minutes, but I didn’t think that we were playing poorly,” Kelly said. “The shots aren’t always there. We seemed to get rolling after that and I thought we played a pretty consistent game.”

Boston got goals from three different lines and the six assists came from six players.
