With the game tied at 3 in overtime, Boston's Riley Nash took a penalty for roughing at the 4:38 mark of the period to give the Senators a power play. Ottawa added another goal early in the second before Boston produced a dramatic comeback. Craig Anderson made 17 saves. "I think it was pretty selfish of me", Nash said. He was in the penalty box for roughing when Bobby Ryan produced the victor in Game 3 to give the Senators a 2-1 series lead.
This time, the Bruins rallied from a 3-0 deficit with three goals in the second period, tying the game on a power-play goal by David Pastrnak.
Anderson stopped all nine shots Boston sent his way in the third and Rask brushed aside seven to send the game to overtime. "We had many opportunities to end it in the third".
"Yeah, I agree with you 100 percent - demoralizing", he said. "You can't make that play". "But when he does get his chance, he's going to have to prove he can stay in the lineup". Backes stole the puck from Ryan and netted another goal 42 seconds later to make it 3-2.
It almost nullified what was a dominant start by the Senators, who kept the action on their side of the red line for most of the first period.
The Bruins will look to make it two wins in a row without Krejci.

"Momentums are insane", Anderson said.
