Joe Pavelski's return from a broken foot provided a jolt to the San Jose Sharks and helped deliver a convincing victory over the Stanley Cup champions. Pavelski had a goal and an assist in his first game back from the injured list, Evgeni Nabokov made 27 saves in his 49th career shutout and the Sharks beat the Pittsburgh Penguins for the seventh straight time at home, 5-0 Saturday night.
