They are playing for pride in this one.
Neither the Bruins or the Capitals can improve their playoff positioning in the regular season finale on Sunday. Washington wrapped up the No. 1 seed in the Eastern Conference long ago while the Bruins are stuck in the sixth slot with 89 points after the Canadiens lost in overtime to the Maple Leafs on Saturday night.
But the game will still be played and Boston is looking to not get swept by Washington this season, having dropped the first three games in the series with a combined score of 11-4.
It did not look promising early for the Bruins as Alexander Semin beat Tim Thomas  at 2:23 with a snap shot that the reigning Vezina Trophy winner could not corral to give the Caps the early 1-0 lead.
Boston came back at 5:29 when Milan Lucic  fought hard for the puck for the behind Washington goaltender Semyon Varlamov and backhanded a pretty pass in front to the stick of Michael Ryder  who went back across Varlamov for his 17th goal of the year. Zach Hamill, Boston’s first round pick (No. 8 overall), who is making his NHL  debut, got the secondary assist on the goal for his first NHL  point.
Ryder, who had not scored since March 16 against Carolina, broke another bad Bruins streak when he snapped their scoreless power play funk at 0 for 22 at 14:55 after Alexander Ovechkin went to the box for high sticking at 14:27.
The Bruins could not hold the lead for long though as the Capitals came back with a goal 19-seconds later when Eric Belanger beat Thomas with a wrist shot at 15:14 to tie the game at two.
That is where it stands heading into the second. Washington leads the Bruins in shots by the slimmest of margins, 9-8.
