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.
