SAN JOSE, California (Reuters) - San Jose netminder Evgeni Nabokov stopped 27 shots for his 49th career shutout as the Sharks crushed the Pittsburgh Penguins 5-0 in an early season clash of NHL division leaders on Saturday.

Joe Pavelski, returning from a broken foot, joined Dan Boyle and Manny Malhotra as each delivered a goal and an assist to help the Pacific Division-leading Sharks remain unbeaten in five regulation games at home this season.

Jamie McGinn and Dany Heatley also scored for San Jose.

Pittsburgh, the Atlantic Division's top team and defending Stanley Cup champion, lost on the road for only the second time in nine games.

McGinn and Pavelski, the latter on a powerplay, gave San Jose a 2-0 first period lead. Boyle and Heatley made it 4-0 in the second with Heatley netting his 11th goal of the season.

Malhotra scored on another powerplay in the third.
