Petry gave the Canadiens a 2-1 lead with nine seconds left in the second period. The defenseman has six points (two goals, four assists) in a four-game point streak and 10 points (two goals, eight assists) in his past 10 games. Petry had 16 points (four goals, 12 assists) in his first 57 games. He has 26 points (six goals, 20 assists) in 67 games after scoring at least 40 points in each of the previous four seasons.
"It wasn't my goal at all this year to show up and play the way I did at the start of the year, so for me it was just pushing through and trying to find that game that I had the previous three years," Petry said. "I'm glad that it's starting to show now."
St. Louis said of Petry, "I feel like he's sprinting to the finish line after a long race, and I like that. He's not just coasting through it. He's putting himself in a better mental situation I guess with his season that can carry into his summer. I'm really happy for him."
