TORONTO (AP) - Nick Schmaltz scored the winner on a power play with 6:48 left in regulation and the Utah Mammoth beat the Toronto Maple Leafs 3-2 on Tuesday night.

Dylan Guenther and Andrew Peeke also scored for Utah. Sebastian Cossa made 27 saves. Clayton Keller added three assists and Mikail Sergachev had a pair.

Jack Roslovic scored twice for Toronto, which got 33 stops from Sergei Bobrovsky. Auston Matthews assisted on Roslovic's goals.

Schmaltz snapped a 2-all tie when he buried a loose puck in the crease on the man advantage after Bobrovsky made a huge stop on Keller.

Down 2-1 in the third period, the Maple Leafs tied it at 9:05 when Rosolvic moved in alone on Cossa and scored his second of the night on a backhand shot.

A two-time Stanley Cup champion signed over the summer to a big-money deal in free agency for the next three seasons, Bobrovsky entered with a 3-5-2 record, .885 save percentage and a 3.29 goals-against average.

The 38-year-old, who had allowed three goals or more in nine of 10 starts entering Tuesday, was helped out by some posts in the first, but could do nothing against the NHL´s top-ranked power play when Guenther shot through a screen with 12.4 seconds left on the clock in the first.

Toronto tied it at 10:20 of the second when Roslovic scored past Cossa moments after Maple Leafs defenseman Troy Stecher´s stick exploded on an odd-man rush before Peeke pushed the visitors ahead with a controversial goal at 13:42.

Peeke´s blast through traffic beat Bobrovsky at 13:42 of the second for a 2-1 lead. Mammoth center Barrett Hayton appeared to interfere with the netminder when their skates touched, but the officials ruled the sequence a good goal. The Maple Leafs then declined to challenge and risk a minor penalty.

The Mammoth will have played 13 of their first 19 games on the road before returning home on Nov. 12 against the St. Louis Blues.

Mammoth: At Montreal Canadiens on Thursday.

Maple Leafs: Host the Montreal Canadiens on Saturday.
