Facing the speedy San Jose Sharks, Randy Carlyle knew his Toronto Maple Leafs had to be ready to skate.
For stretches, they did. But penalties stunted Toronto's momentum and helped San Jose to a 4-2 victory Tuesday night at Air Canada Centre, the Leafs' fifth straight loss.
The Sharks (19-3-5) won their sixth consecutive game and ninth in their past 10, outshooting the Leafs 41-30.
Former Leafs forward Mike Brown, Joe Thornton, Brad Stuart and Logan Couture scored for the Sharks. Mason Raymond and Phil Kessel scored for Toronto (14-11-3).
Early on, it looked like the Leafs would be able to hang with the Sharks as they put up the game's first three shots. Then a roughing penalty to Frazer McLaren gave San Jose a boost.
The Sharks didn't score on the ensuing power play, but they didn't give the puck up much for the rest of the period. Brown opened the scoring exactly midway through the first, tipping a shot from defenceman Jason Demers past Leafs goaltender James Reimer.
Centre Nazem Kadri missed the game because of the death of his grandfather.
The Leafs also held a pre-game moment of silence for Toronto police constable John Zivcic, who died from injuries he sustained in a car accident on Saturday.
