New Jersey : The New Jersey Devils hammered Florida 4-0 to level their Stanley Cup play-off series on Thursday while in the Western Conference Phoenix earned a 3-2 overtime win over Chicago to go 3-1 up in their best-of-seven series.

In Washington, the Capitals overcame the absence of Nicklas Backstrom to beat the Boston Bruins 2-1 and level their Eastern Conference first round series at 2-2. The St.Louis Blues beat the San Jose Sharks 2-1 to give them a strong 3-1 lead in their Western Conference series.

New Jersey goaltender Martin Brodeur recorded an NHL record 24th career play-off shutout to frustrate the Panthers in Newark and level the series at 2-2.

Zach Parise scored 6:08 into the second period with a deflection off a long-range slap shot from defenseman Marek Zidlicky on the power play to give the Devils the advantage.

New Jersey opened up the game in the third period thanks to a thundering effort from Steve Bernier and goals from Travis Zajac and Ilya Kovalchuk to ensure a convincing victory.

The fifth game of the series takes place in Florida today.

All four games between the Chicago Blackhawks and the Phoenix Coyotes have needed overtime to separate the teams and for the third time Phoenix came out on top. Mikkel Boedker again got the overtime winner, following his game-deciding goal on Tuesday, giving the Coyotes a chance for their first series win since they moved to Arizona.

Third period goals from Shane Doan and Taylor Pyatt had put Phoenix 2-0 up but Chicago fought back with a goal from Brendan Morrison before Michael Frolik put home a rebound with just 1:26 left in regulation to force overtime.
