Tuukka Rask will take another shot at closing out a playoff series today when the Boston Bruins host the Rangers for Game 5 of the Eastern Conference semifinals. Rask is only 26, but he’s already dangerously close to becoming known as a goaltender that can’t finish. After a head-scratching performance in a 4-3 overtime loss to the Rangers in Game 4 on Thursday night, Rask is now 2-8 with a 3.20 goals-against average and .890 save percentage in his career in games in which his team can close out a playoff series. Conversely, the Rangers are 6-1 in elimination games over the past two seasons, but were there for the sweeping Thursday night. They appeared dead, trailing 2-0 in the second period with only six shots on goal, before Rask tripped and fell on his butt, allowing Carl Hagelin’s seemingly harmless deflected shot to trickle by him and over the goal line. "Got to be more focused," Rask said afterward. He could have said similar after his nonchalance contributed to Derek Stepan’s tying goal 1:15 into the third period. Rask left the puck behind the net for Zdeno Chara and casually coasted back into his crease as Stepan stripped Chara of the puck and deposited it in the net. If this was another goalie on another team, you’d dismiss it as one unfortunate game, but another one like it today will stir up all of the Bruins’ bad memories from 2010. Rask was the goalie that year when the Bruins blew a 3-0 series lead to Philadelphia in the conference semifinals.
