Ottawa Senators at Chicago Blackhawks

Connor Bedard scores 3 times as the Blackhawks knock off the Senators 7-3

Frank Nazar and defenseman Louis Crevier each had a goal and an assist for Chicago in its third win in four games. Ryan Donato and Colton Dach also scored.

Bedard took Ryan Greene’s short pass and whipped a 25-foot wrist shot past Linus Ullmark for a 5-3 Chicago lead 3:46 into the final period. It completed his first NHL hat trick in his 160th career game on a night when he became only the seventh Blackhawks player to score at least 50 goals before turning 21.

Ottawa had won three in a row. Tim Stutzle had a goal and an assist for the Senators, and Jake Sanderson also scored.

Bedard’s exploits made up for the Blackhawks’ second-period swoon, when they allowed three goals on as many shots in 3:33, letting the Senators back into the game.

Sanderson beat Spencer Knight on a 55-foot slap shot that caromed off the end boards and Knight’s left elbow. Michael Amadio got his second of the season at 7:09, and Stutzle made it 4-3 with a wrist shot from the right circle at 8:31.

The Blackhawks had built a 4-0 lead on Dach’s rebound shot off a Crevier drive, followed by a Crevier goal that caromed off Ottawa’s Nikolas Matinpalo, and Bedard’s first two goals, the first on a power play, the second a wrist shot past Ullmark 2:58 into the second period.

Knight stopped 21 shots, and Ullmark made 19 saves.

Chicago captain Nick Foligno reached 600 career points with his assist on Dach’s goal.

Up next Senators: Host Calgary on Thursday night.

Blackhawks: At Winnipeg on Thursday night.
