The Pittsburgh Penguins will take on the Boston Bruins in Game 4 of their NHL Stanley Cup 2013 Playoff Eastern Conference Finals series on Friday night. The Penguins are already on the brink and seriously struggling at 0-3 down. They need to win or go home tonight.

The Bruins will be looking to keep up the momentum and complete a sweep against their Pittsburgh rivals. If they can win tonight at TD Garden then they will clinch the 2013 Eastern Conference title, and move on towards the Stanley Cup Championship Game against the Western Conference winner.

The Bruins have been excellent; hugely impressive through Game 1, and followed that up with a near perfect performance in Game 2.

In Game 3 things were much tighter but the Bruins again came out on top in double overtime to leave the Penguins on the brink.

This is certainly not how many would have predicted the series would go before it started. The Penguins are undoubtedly one of the most talented sides in the NHL, and even though they face elimination at the end of a long season tonight, they are probably one of the only teams pundits would believe could possibly come back from a 0-3 series scoreline.

If the Penguins can win tonight they will hope it is the start of a change in momentum, and if things do swing back their way then they can be hard to stop for any side. The Penguins need to win four consecutive games now to clinch the conference title, and it has to begin tonight. It is do or die time.
