Murray took a feed from R.J. Umberger and beat backup goalie Jeff Zatkott. Murray was the No. 2 pick in the 2012 NHL draft but missed the season with a shoulder injury.
Chuck Kobasew got Pittsburgh even 4-4 at 13:05 of the third period with a power-play goal — his second tally of the game. Mark Letestu and Cam Atkinson scored 30 seconds apart earlier in the period to give Columbus a 4-3 lead.
Dustin Jeffrey's power-play goal for Pittsburgh had made it 3-2 at 4:19.
That was something I've been dreaming of, something I've told myself before the third period I was going to do ... It was an amazing feeling. It's hard to describe. I didn't believe it went in at first but when I saw all the reaction and all the fans going crazy and my teammates going crazy, it's just an unbelievable feeling. I didn't know what to do. I didn't know whether to jump or just skate and do a Theo Fleury. I don't think I'm the same caliber player he is so I couldn't do it.
