The goal was McCann's 400th NHL point.
After a Matty Beniers slap shot from the high slot hit Vegas goaltender Adin Hill in the chest, it dropped to McCann at the top of the crease. McCann swatted it into an open net as Hill fell to the ice.
“I knew there wasn’t much time on the clock,” McCann said. “Matty made a great play, obviously, turned back and created space from the guy, and I just tried to do the same at the net.”
Beniers also scored, and Vince Dunn had two assists for the Kraken (2-0-0), who have won their first two games of the season for the first time in franchise history. Joey Daccord had 26 saves.
Seattle entered the game with a 3-11-1 record in franchise history against Vegas.
“They’re a good hockey team, we know that,” Seattle coach Lane Lambert said. “Past is past, I guess, so to speak. It’s important for our team to understand that what we’re doing is a formula to have success. You’re not always going to win, and that’s the way it goes. The outcome was great, but had it been slightly different, I wouldn’t have been unhappy with our hockey team’s effort.”
