OTTAWA, Ontario - Tom Pyatt, Mark Stone, and Chris Kelly had a goal and an assist each as the Ottawa Senators defeated the Arizona Coyotes 7-4 on Tuesday night in front of a sparse crowd of 11,061 at Canadian Tire Centre.

Bobby Ryan, Zack Smith, Kyle Turris, and Erik Karlsson, into an empty net, also scored for the Senators, who have won three of four. Mike Hoffman had three assists and Craig Anderson made 31 saves.

Jordan Martincook scored twice, including his second at 18:43 just 30 seconds after Turris gave the Senators a 6-3 lead.

Tobias Rieder and Oliver Ekman-Larsson had the other goals for the Coyotes

Arizona lost the services of starting goalie Mike Smith seven minutes into the third period when he suffered an injury to his left leg during a scramble in front of the net.

Smith, who had stopped 27 of 30 shots before getting hurt, was replaced in the goal by Louis Domingue, who surrendered two goals on the first three shots he faced less than a minute after entering the game.

Kelly capitalized on a giveaway and beat Domingue from in close at 7:30 and then Stone scored on a rebound at 8:11, giving the Senators a 5-2 lead.

Domingue finished with eight saves.

Martincook pulled the Coyotes within two at 10:07.

Ekman-Larsson had cut the Senators' lead to 3-2 with a power-play goal just 61 seconds into the third period.

Zack Smith scored a shorthanded goal to give the Senators a 3-1 lead.

On his goal Smith got a great backhand pass from Pyatt and scored with a quick shot at 13:04. It was Smith's second goal of the season as he works to try and duplicate his career-high 25 goals from last season.

The Coyotes had opened the scoring in the first period when Rieder beat Anderson on a rebound from the slot.

The Senators are 3-0-0 at home this season and will host the Tampa Bay Lightning on Saturday before heading out on a three-game Western swing.

The Coyotes continue their season-long six-game road trip in Montreal on Thursday.
