TORONTO — Nazem Kadri tied the score late in the third and then had the winner in the shootout to lift the Toronto Maple Leafs to a 3-2 victory over the Pittsburgh Penguins on Tuesday night.

Viktor Stalberg also scored in regulation for Toronto (4-1-0).

Ryan Bayda and Chris Conner scored for the defending champion Penguins (1-2-2).

Pittsburgh was 68 seconds away from winning the game in regulation, before Kadri sneaked in off the wing and buried a rebound over Penguins goalie John Curry to tie it 2-2. It was the longshot rookie's second goal of the preseason.

"Hopefully, I'm making the decision hard," Kadri said. "I appreciate (coach) Ron (Wilson) giving me the opportunity to go out there in some big situations. I think it's really building my confidence."

The Penguins were without stars Sidney Crosby, Evgeni Malkin and Marc-Andre Fleury, dressing just five players who appeared in Game 7 of the Stanley Cup finals.

However, Pittsburgh came out with plenty of energy and got an early jump on the Maple Leafs. The Penguins worked the puck around Toronto's end for a full shift before Bayda lifted a backhander over Vesa Toskala 1:43 into the game.

"We had a puck stop on the goal-line tonight and we had a couple of other good chances," Penguins coach Dan Bylsma said. "That's what you want to see in the preseason. You want to be generating chances and seeing how the team plays in its own zone."

It was a big goal for Bayda, the 28-year-old from Saskatoon, Saskatchewan, who is attending training camp on a tryout after spending eight years in the Carolina Hurricanes organization.

Conner, another bubble player fighting for a spot with the Penguins extended the lead to 2-0 with his second goal of the preseason. The former Dallas Stars winger found himself with a long breakaway when Leafs defenseman Mike Komisarek pinched in from the point and Conner beat Toskala with a nice backhand deke at 12:48.

Notes: The announced attendance was 18,910 — roughly 7,000 more than the Toronto Blue Jays drew down the street at Rogers Centre.
