Alex Killorn scored the go-ahead goal in the third period and also had an assist as the Anaheim Ducks scored three unanswered goals to rally for a 3-2 victory over the Montreal Canadiens on Sunday afternoon.

Mason McTavish and Frank Vatrano also scored goals and Leo Carlsson had two assists for Anaheim, which won for the fourth time in its last five games. Lukas Dostal finished with 21 saves as the Ducks improved to 21-0-2 when scoring three goals or more in a game.

Joel Armia and Christian Dvorak scored goals and Sam Montembeault made 19 saves for Montreal, which lost its fifth straight game.

Montreal, playing the first game of a three-game California road trip, took a 1-0 lead at the 10:35 mark of the first period on a short-handed goal by Armia. Jake Evans set up the score by poking the puck away from Jackson LaCombe at the offensive blue line and then finished an odd-man rush with a crossing pass to Armia cutting in front of the net, who put a wrist shot past Dostal’s glove side.

The Canadiens increased the lead to 2-0 later in the period on a power-play goal by Dvorak. He shoveled in a rebound of Mike Matheson’s point shot.

Anaheim, playing without top scorer Troy Terry (illness), rallied to tie it in the second period with two goals in a 40 second span.

McTavish got the first when he redirected Killorn’s shot from the top of the right circle inside the right far post for his seventh goal in six games. Vatrano followed with his fifth goal in six games with a wrist shot from the edge of the left circle off a drop pass from Ryan Strome.

Killorn then put Anaheim ahead 3-2 at the 11:11 mark of the third period when he ripped a wrist shot from the center of the right circle through traffic, off the far post and in for the game-winner.

Montreal pulled Montembeault for an extra attacker with 2:07 remaining and Dostal turned aside three shots to seal the win.
