The Penguins call defenseman Douglas Murray a needed element -- big, physical and a menace for opponents intent on playing in front of his team's net.

But what should the team and its fans call him more casually? Doug? Douglas?

"Doesn't matter," Murray said Wednesday after practicing with his new teammates for the first time. "They can call me whatever they want, just as long as they cheer for me and don't boo me."

Murray arrived Tuesday night after the Penguins acquired him Monday in a trade with the San Jose Sharks.

"They asked me what I want to be called. I said I don't care," he said. "I've had so many nicknames throughout the years. But the one that actually stuck was Crankshaft. That turned into Cranky, which I don't like because I'm not a cranky person."

Why Crankshaft?

"That's a story that I've never been told and never will be told," he said with a smile.

Murray is expected to make his Penguins debut tonight against the Winnipeg Jets at Consol Energy Center.

Although he will be working on a learning curve in the short term as he gets acclimated to the Penguins system, if he is nearly as effective and punishing a player as the Penguins expect, he might get called a lot worse than Crankshaft by the Jets.

"I try to be physical," said Murray, who at 6 feet 3, 245 pounds likely couldn't play any other way.

"I've played in the league for some time now. I hope I can keep my emotions in check so I don't try to run around and get out of position. I think that's something I've improved on -- letting the hits come to you instead of trying to get them."

Murray, 33, had 56 hits and 64 blocked shots in 31 games for the Sharks. Last season, he led San Jose with 126 hits and was second with 143 blocked shots.
