TORONTO (AP) _ Mike Johnson and Igor Korolev scored in the second period to lift the Toronto Maple Leafs to a 2-1 victory over the Buffalo Sabres on Saturday night.

Alexei Zhitnik scored in the first period for Buffalo, which had a nine-game undefeated streak snapped (6-0-3).

Korolev beat Sabres goaltender Dominik Hasek on a breakaway at 12:32 of the second period, breaking a 1-1 tie and giving the Maple Leafs (10-8-2) sole possession of first place atop the Northeast Division. The Sabres (8-4-4) are two points back but have four games in hand.

The Maple Leafs were 1-6-3 against Buffalo in 10 previous meetings, and had lost three times to the Sabres this season, including 4-1 Friday night in Buffalo. This time, they outshot the Sabres 31-18.

Curtis Joseph was the winning goaltender.

After falling behind 1-0 on Zhitnik's shorthanded goal, the Maple Leafs stormed back in the second period, outshooting the Sabres 14-5. Alyn McCauley, who fired wide on two partial breakaways in the first, set up Johnson's goal that tied the game.
