Bobby McMann registered the first hat trick of his NHL career as the short-handed Toronto Maple Leafs defeated the St. Louis Blues 4-1 on Tuesday night.

William Nylander had the other goal for Toronto. Ilya Samsonov made 14 saves.

The NHL’s department of player safety announced shortly before the opening faceoff it had suspended Leafs defenseman Morgan Rielly five games for his cross-check to the head of Ridly Greig following the Ottawa center’s slapshot empty-net goal in the final seconds of the Senators’ 5-3 victory Saturday.

The Leafs were also missing star forwards Mitch Marner and John Tavares, who were ruled out just before warm-ups due to illness.

The undrafted 27-year-old winger has shown offensive flair at lower levels, but it had been a challenge in the NHL through his first 36 games, especially on a team where he’s battling for time further down the lineup.

Alexey Toropchenko scored for St. Louis, which entered 7-1-0 over its last eight games. Jordan Binnington stopped 28 shots in defeat

The Blues host the Oilers on Thursday.
