(AP) — Antti Niemi earned his 30th NHL shutout, and third of the season, with 28 saves, Joe Pavelski scored his second goal of the game during a two-man advantage, and the San Jose Sharks beat the Anaheim Ducks 3-0 on Wednesday night. San Jose center Joe Thornton left with an undisclosed injury in the first period after a collision with Ducks defenseman Clayton Stoner. The six-time All-Star has played every game for the Sharks during the previous three seasons and all 38 this season. Perry took a slap shot just before the second period ended. Anaheim captain Ryan Getzlaf threw his stick against the glass behind the empty bench as he went to the dressing room, and was assessed an unsportsmanlike conduct penalty — resulting in a 5-on-3 power play for San Jose to start the third.
