Defenseman Luca Cagnoni scored at the 2:08 mark of overtime to give the San Jose Sharks a 3-2 preseason win over the Anaheim Ducks on Thursday at the Honda Center.

Klim Kostin drove towards the Ducks net and later gave the puck to the 19-year-old Cagnoni, who fired a shot past Ducks goalie Calle Clang for his first preseason goal.

Kostin had a goal and an assist, and both Danil Gushchin and Ethan Cardwell had two assists in the win, the Sharks’ first of the preseason.

Kostin scored a power-play goal with 2:41 left in regulation time to tie the game 2-2.

After taking a pass from Kasper Halttunen, Gushchin skated behind the Ducks’ net and fed it in front to Kostin, who beat Clang for his first goal.

Leo Carlsson broke a tie with a power play goal early in the third period to give the Ducks a 2-1 lead.

With Sharks forward Quentin Musty serving a hooking penalty, Carlsson took a pass from defenseman Jackso Lacombe and beat goalie Georgi Romanov with 14:39 left in the third period.

The Sharks’ first goal came from forward Tristen Robins at the 2:31 mark of the second period.

Cardwell, who has had a strong preseason, dug the puck out of the corner and got it out front to Gushchin. He slid it over to Robins, who beat Ducks goalie Lukas Dostal from in close for his first goal of the preseason.

Romanov, playing in his second exhibition game, made 22 saves in the first two periods and finished with 32 stops as the Sharks improved to 1-2-0 in the preseason. Nine of Romanov’s saves came on the penalty kill.

Their next preseason game is Tuesday at home against the Utah Hockey Club.

By that time, the Sharks are expected to reduce training camp roster to a more manageable size. The Sharks entered Thursday with 56 players in camp, including 32 forwards.
