New Jersey goaltender Martin Brodeur set an NHL record 24th career playoff 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.

The fifth game of the series takes place in Florida on Saturday.
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.

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.
Boedker then produced a moment of outstanding skill and strength to muscle his way past the defense before sliding the puck through netminder Corey Crawford's pads in overtime.
