OTTAWA -- James Reimer made 49 saves as Toronto Maple Leafs defeated the Ottawa Senators 4-1 on Saturday to qualify for the NHL playoffs for the first time since 2004.

James van Riemsdyk, with two, Nazem Kadri and Joffrey Lupul scored for Toronto (25-15-5). Phil Kessel and Cody Franson each had two assists.

Jakob Silfverberg replied for Ottawa (24-15-6). Craig Anderson stopped 18 shots in taking the loss.

Toronto sits alone in fifth place in the Eastern Conference with 55 points, while Ottawa dropped to seventh (52 points) after the New York Islanders (53 points) jumped into sixth with a 5-4 shootout win at Winnipeg earlier Saturday.

Reimer, who has been stellar for Toronto in recent weeks, continued to dominate the Senators, improving his overall record against Ottawa to 8-1-1 and a perfect 6-0 at Scotiabank Place.

With Ottawa dominating on the shot clock but trailing 2-1, Kadri gave the Maple Leafs a two-goal with a shot at 14:11 of the third that Anderson should have stopped.

Lupul then put the game away for good with a breakaway goal that Anderson got a piece of with less than two minutes to go.

After a scoreless first period, the Leafs led 2-1 lead after 40 minutes thanks to a pair of goals by van Riemsdyk. The big left-winger opened the scoring at 8:22 with a deflection of a Franson point shot before doubling the Toronto lead on the power play by shovelling home a rebound at 12:24.

After some great pressure in the Toronto end late in the second, the Senators were rewarded when Silfverberg's shot from just inside the blue-line beat Reimer with 42.7 seconds remaining in the period.

The Senators outshot the Leafs 17-5 in the first, but many of those came from the outside.

The Maple Leafs looked to have taken a 1-0 lead midway through the period, but a potential goal was called back due to incidental contact by Toronto's Leo Komarov on Anderson.

Minutes later, Erik Condra had two great chances on Reimer but put the puck directly into the Toronto goalie's pads.
