Owners of the longest win streak in the NHL this season, the Pittsburgh Penguins made another move to bolster their lineup on Monday by acquiring defenseman Douglas Murray from the San Jose Sharks.

All the Penguins surrendered in return are second-round draft picks in 2013 and 2014. The latter selection is conditional, hinging on whether or not Murray re-signs with Pittsburgh.

Murray, 33, spent his entire career in the Sharks organization, after the club took him in the eighth round of the 1999 draft. He made his NHL debut in 2005, and has totaled 59 points and 361 penalty minutes in 451 games in eight pro seasons.

"We have tremendous respect for Douglas as a hockey player and a person," said Sharks general manager Doug Wilson. "He has been a warrior for our hockey club for the past eight seasons and he has been in the Sharks family for the past 14 years. This deal places Douglas in a quality situation which he deserves."

A native of Sweden and four-year starter with Cornell University, the 6- foot-4, 240-pound Murray's presence adds an additional solid stay-at-home element the Pens have lacked since Hal Gill helped the franchise to its third Stanley Cup title in 2009.

This deal comes on the heels of a Sunday transaction with the Dallas Stars, which netted the Eastern Conference leaders veteran forward Brenden Morrow.

Pittsburgh has won 12 straight games following a 2-1 overtime decision against the Flyers on Sunday night.
