"Bruins will be on the power play" is not only music to the ears of fans, it's also striking fear into the hearts of the St. Louis Blues.

Game 4 of the Stanley Cup Finals is set for tonight in St. Louis. Puck is scheduled to drop shortly after 8pm EST. Some luck fans will be sipping a fresh "Black & Gold" from Sam Adams, available today. After skating to a huge win in game 3, the Boston Bruins now lead the series 2 games to 1.

The Bruins have been magnificent on the power play. So much, that's they are currently on a historic run with this not so secret weapon. According to Boston.com, Boston’s  power play has converted on 35.9% of its opportunities and the Bruins could be the first unit to finish over 30% in the postseason since the 1981 champion New York Islanders.

The Bruins have stepped it up as the series plows on. After going 2 for 10 in games 1 and 2, they scored 4 power play goals in a 7-2 game 3 triumph.
