The city of Toronto is set to play host to the men's draw of the Rogers Cup, and the event was kicked off with the Sportsnet Ball Hockey Challenge. 

Among those participating were Jason Spezza of the Dallas Stars, and, as seen below, Phil Kessel of the hometown Maple Leafs.

The Leafs sniper spent some time chatting with tennis legend Roger Federer, who may or may not have been giving Kessel some forehand swing tips should the likes of John Scott give him any trouble in the future.

The caption, in typical Kessel fashion, read, "Ball hockey with Roger Federer."
