Defenseman Brandon Montour scored with 34 seconds left and the Seattle Kraken beat the Toronto Maple Leafs 5-4 on Wednesday to spoil No. 1 overall pick Gavin McKenna’s first two-goal game and three-point night.

After scoring on power plays in each of the first two periods, McKenna helped set up Auston Matthews’ tying goal with 1:30 remaining and goalie Sergei Bobrovsky off for an extra attacker.

Montour then beat Bobrovsky with a slapper from the top of the right circle.

Chandler Stephenson had a goal and an assist to help Seattle improve to 8-4-1. Ryker Evans, Berkly Catton and Josh Mahura also scored, and Philipp Grubauer made 18 saves.

Stephenson gave Seattle a 3-2 lead on a power play at 3:33 of the second period, and assisted on Evans’ goal with 9:02 left.

McKenna has five goals in 15 games this season. Matthews has 10 goals.

Jack Roslovic also scored for the Maple Leafs, cutting it to 4-3 at 8:02 of the third period.…
