Tomas Hertl scored a late tie-breaking goal in third period to give the Sharks a 3-1 win over the Chicago Blackhawks on a night Patrick Marleau moved one goal shy of 500 for his career.
Hertl scored his fifth goal of the season in front after defenseman Brent Burns sent a hard carom off the end boards that ricocheted past Joe Thornton to Hertl, who was playing only his second game after missing 32 with a knee injury.
Captain Joe Pavelsi added an empty-net goal with 45.
