Matthew Kessel scored his first NHL goal in his 37th game to give the Blues a 2-1 lead at 12:36. He took a centering pass from Thomas and beat Dostal with a wrist shot from the slot.
"It's taken a couple games, for sure, but it's great to get that one," Kessel said. "It was obviously a good little play in the neutral zone there, and then Schenn was able to drop it off to Thomas and gave it to me in the middle of the ice joining with a bunch of room, so I was pretty much just able to take it down and shoot it."
Vatrano tied it 2-2 at 3:41 of the second period when he stuffed in a loose puck in the crease.
Thomas put the Blues back in front 3-2 at 13:36 with a wrist shot from the right circle on a power play.
"’Boldy’ played excellent," Thomas said. "He was hard on pucks, he made a ton of plays and he really created a lot of space for me. Him and ‘Schenner’ did a great job of that, so a lot of credit should go to those two guys."
