Boris Katchouk scored in the ninth round, Petr Mrazek made the clinching save on San Jose’s Filip Zadina, and the Chicago Blackhawks beat the Sharks 2-1 in a shootout on Tuesday night.

Chicago broke a three-game losing streak in the matchup of the NHL’s two worst teams while sending San Jose to its third straight defeat and 15th loss in 16 games.

Chicago’s Rem Pitlick and San Jose’s Kevin Labanc scored in the first two rounds of the shootout, after which both teams misfired more than they were saved.

Katchouk beat Mackenzie Blackwood on a backhand by his right toe for the winner. Cole Guttman scored for the Blackhawks and Mrazek had 37 stops, his fourth straight game to allow two or fewer goals.

The Blackhawks are at Buffalo tonight.
