TORONTO (AP) – Dany Heatley scored the go-ahead goal in the third period and the Ottawa Senators again showed their dominance of the Toronto Maple Leafs with a 4-2 victory.

Patrick Eaves, Brian Pothier and Zdeno Chara also scored for the Senators, who have won all seven games against Toronto this season – outscoring the Maple Leafs 40-14.

Alex Steen and Alex Ponikarovsky had goals for the Maple Leafs, who have lost five straight.

Toronto – 4-14-2 since Jan. 6 – is in danger of missing the playoffs for the first time in coach Pat Quinn’s seven-year tenure.

The Maple Leafs suffered another blow as Eric Lindros didn’t play in the third period after reinjuring his wrist. He already missed 26 games earlier this season with the injury.

Heatley scored his 36th goal by sending a one-timer past 40-year-old goalie Ed Belfour at 4:24 of the third period.

Toronto had a power-play opportunity with 15.1 seconds left. After the Maple Leafs called a timeout, Ottawa won the faceoff back to Chara, who shot the puck the length of the ice for an empty-netter

Toronto’s Chad Kilger made a backhanded pass from behind the net to Steen, who scored at 11:54 of the first.

After checking his man behind the net, Eaves skated in front and put a rebound past Belfour at 3:08 of the second.

Just over a minute later, Pothier’s shot from the point deflected off Toronto defenseman Aki Berg and past Belfour.

But Ponikarovsky tied it after Ottawa’s Chris Kelly turned the puck over around his net, allowing Ponikarovsky to score after a rebound at 8:08 of the second.
