TORONTO – Joe Thornton had two assists for the second straight night with his new team, helping the San Jose Sharks rally to a 5-4 victory over the Toronto Maple Leafs.

Alyn McCauley scored twice for the Sharks, who ended a 10-game losing streak Friday with a 5-0 win at Buffalo – Thornton’s debut with San Jose after being traded by Boston on Wednesday.

Mark Smith, Scott Hannon, Patrick Marleau had the other goals for the Sharks.

Darcy Tucker, Eric Lindros, Matt Stajan and Jason Allison scored for the Maple Leafs, who have lost two of three.

Toronto captain Mats Sundin assisted on Tucker’s goal, giving him 769 points with Toronto – surpassing Borje Salming for second on the team’s career list.

Maple Leafs goalie Ed Belfour could have become the NHL’s second winningest netminder with a victory but he allowed four goals on 27 shots. Belfour is tied with Terry Sawchuk at 447 wins.

Smith scored a short-handed goal by skating in alone and putting a slap shot past Belfour’s blocker, giving San Jose a 4-3 lead at 11:46 of the second period.

Hannon scored the first goal of the game with a shot from the side of the net at 4:06 of the first, but Toronto followed with three straight.

The Sharks took the lead in the second with three consecutive goals of their own on just eight shots against Belfour.

Marleau put his own rebound in at 5:34 of the second, McCauley scored on one-timer in front of the net and Smith gave San Jose the lead for good.

McCauley, a former Leafs player, gave San Jose insurance with a backhanded goal from in front at 14:15 of the third.

Allison scored on a wraparound with 2:39 left, but the officials didn’t immediately rule it a goal. After a long delay they agreed to review the play. The video replay showed the puck crossed the line before goalie Vesa Toskala got his stick on it.

Scott Thornton, Joe’s cousin, then received a delay-of-game penalty for clearing the puck into the stands.

The Maple Leafs called a timeout, emptied their net and put out an extra attacker but Joe Thornton cleared the puck from San Jose’s end, ensuring the victory.

Notes: San Jose goalie Evgeni Nabokov didn’t play after straining a groin Friday. Toskala made 24 saves in his place. … Lindros has 11 goals in 28 games with the Maple Leafs, his hometown team. … The Leafs had won six of seven home games. … Joe Thornton has just eight penalty minutes this season
