Checking-line forward Colin Greening scored at 12:21 of double overtime as the Senators defeated the Penguins 2-1. Pittsburgh still lead the series 2-1. It was the longest game played so far in the 2013 Stanley Cup Playoffs and the first to go to double overtime.
It was also a great comeback game for Senators goaltender Craig Anderson, who made 49 saves in between the Ottawa pipes.
In the other Eastern conference semi-final, the Boston Bruins defeated the New York Rangers 5-2 to take a 2-0 series lead. The Bruins were led offensively by Brad Marchand and Torey Krug, who each notched a goal and an assist, and by David Krejci and Patrice Bergeron who each notched two assists.
