The Sharks allowed a go-ahead goal to Pierre Engvall with 2:27 left in the third period in a 3-1 loss to the Toronto Maple Leafs on Wednesday at Scotiabank Arena.
Tomas Hertl had the puck in the neutral zone but had a backhand pass intercepted by the Maple Leafs. Alex Kerfoot later put a shot on goal that was saved by Aaron Dell, but the rebound came straight to Engvall, who scored his third of the season to give the Leafs a 2-1 lead.
Matt Nieto scored the only goal for the Sharks, who lost for the fourth time in five games.
