A late goal by Ottawa’s Tom Pyatt held up as the game-winner in the Senators’ 4-3 victory over the Leafs on Wednesday night at Air Canada Centre.

The regulation loss was a disappointing one for the Leafs, who had rallied from earlier two-goal and one-goal deficits to even the score.

Pyatt’s goal was scored on an odd-man rush created when Leafs defender Morgan Rielly made an ill-advised pinch. The error overshadowed what had otherwise been a spectacular outing for Rielly. In 26:15 of ice time, Rielly registered a goal on six shots.

“I felt good. When you’re playing from behind you try to play catch up and then it’s unfortunate when you give one back,” Rielly said. “Just some miscommunication between the forward and I. It’s my fault for going.”

Leafs coach Mike Babcock concurred with the assessment. “I thought (Rielly) was really, really good and he’d probably like to have the mistake back,” Babcock said.

James van Riemsdyk had a career-high eleven shots on goal, scoring once. Andreas Borgman notched his third marker of the year for Toronto.

Despite a strong opening two minutes, plus a third period shift during which he dangled the puck away from four different Senators defenders, Auston Matthews was held pointless. Earlier in the day, Matthews was named the Leafs’ lone representative for this year’s NHL All-Star Game.
