Few matchups bring the edge and intensity of the Battle of Pennsylvania, where the Pittsburgh Penguins and Philadelphia Flyers routinely push each other to the limit. Since 1997, the two teams have met six times in the playoffs, with each side winning three series. One of those showdowns came in the 2009 Stanley Cup Playoffs. In Game 6 of the First Round on the road in Philadelphia, Sergei Gonchar scored his first goal of the postseason early in the third period to break a tie. The goal sealed the series for Pittsburgh, who went on to capture the Stanley Cup later that spring.
