MONTREAL -- Braden Holtby made 22 saves in relief and Lars Eller scored 3:34 into overtime to give the Washington Capitals a 5-4 win against the Montreal Canadiens at Bell Centre on Monday.
Holtby entered the game at 1:35 of the second period after starting goalie Pheonix Copley allowed four goals on 22 shots.
"[Copley] has been playing phenomenal for us," said Holtby, who returned after missing the past three games because of an upper-body injury. "You know, a couple of bounces don't go our way. We know it's not on him, it's on us to pick a teammate up in that situation. And I thought our team really turned it around and started playing some good hockey."

Nicklas Backstrom drew Washington within 4-3 at 13:20. Ovechkin and Brett Connolly scored in the first for the Capitals (10-7-3).
"I think they had a pretty lucky start to the second period, you know, three shots on net and everything goes in," Ovechkin said. "We just regrouped, no panic. We knew we had plenty of time to bounce back. Obviously [Backstrom's] goal was big and we knew one shot away and it's a tie game."
Carey Price made 29 saves for Montreal (11-6-4), including a sensational sprawling save on another Ovechkin one-timer with two seconds left in the third period.
"Carey did everything to keep us in the game," Canadiens coach Claude Julien said. "It may have been five goals against him, but it was thanks to him that we were still in the game."

Ovechkin was impressed enough to applaud Price as he skated past.
"He makes a good save, maybe a lucky save, I don't know, but obviously it was a pretty cool play," said Ovechkin, who has 20 goals in 25 games against Price. "The fans enjoy it, we enjoy it as well."
Canadiens forward Max Domi extended his point streak to 10 games with an assist on Petry's power-play goal at 1:08 of the second, which gave Montreal a 3-2 lead after Gallagher tied it with his 10th goal 20 seconds into the period. Agostino made it 4-2 at 1:35, the last shot Copley faced.
