TORONTO -- James van Riemsdyk picked up his team-leading 13th goal of the season, and Phil Kessel chipped in with a goal and two assists as the Toronto Maple Leafs defeated the Ottawa Senators 5-4 Wednesday night at the Air Canada Centre.
Toronto (15-9-0) extended its winning streak to three games. The Leafs are 11-4-0 in their past 15 games.
Ottawa (12-8-4) fell to 0-2-2 on its current five-game road trip.
The game started on a subdued note. Twenty-six seconds in, Toronto's Frazer McLaren and Ottawa's Dave Dziurzynski dropped the gloves just inside the Maple Leafs' blue line. McLaren knocked out Dziurzynski mid-fight, and the Senators rookie fell to the ice face first.
He lay motionless on the ice for a few moments before Ottawa's training staff was able to help him off the ice. Dziurzynski, who was playing in just his 10th NHL game, suffered a concussion and did not return.
Van Riemsdyk put in the rebound off a Kessel shot 1:20 into the middle period, giving Toronto a 3-0 lead.
Ottawa made it 3-2 thanks to goals by Mika Zibanejad and Zack Smith.
Kessel expanded the Leafs' edge to 4-2 with a power-play goal less than four minutes into the third period.
Toronto's Nazem Kadri extended his point streak to six games with his 10th goal of the season near the midway mark of the third. The unassisted goal pushed the Leafs in front 5-2.
After Ottawa captain Daniel Alfredsson made it 5-3, Colin Greening got the Senators to within one with under two minutes remaining, beating James Reimer with a backhand off a pass from Erik Condra.
With the goaltender pulled and under a minute remaining, Ottawa could not find the equalizer.
Tyler Bozak opened the scoring at 6:24 of the first period, snapping an eight-game goalless drought.
Less than a minute later, Toronto made it 2-0 when Jay McClement scored his fourth of the season.
Zibanejad's goal was his fourth in his past seven games. Smith's goal was his second in his last 57 games dating back to last season.
Reimer made 39 saves en route to the win. Ottawa goalie Ben Bishop stopped 23 shots.
The Maple Leafs improved to 12-1-0 when leading after two periods, while the Senators dropped to 2-5-0 when trailing after 40 minutes.
