Sloane Stephens and her boyfriend, Toronto FC soccer star Jozy Altidore, sat courtside at the Air Canada Centre on Wednesday night for the Raptors-Celtics NBA game.

The 2017 US Open and 2018 Miami Open champion was joined at halftime by Denis Shapovalov for a quick exhibition with the mascot.

Teaming up to take on The Raptor 2-on-1, Stephens and Shapovalov won easily.

Also winning easily were the Raptors, who beat the Celtics 96-78. The game had huge implications, as both teams were fighting for the top seed in the Eastern Conference.

That score can't sit too well with devoted Celtics fan Nick Kyrgios, who commented on Shapovalov's Instagram post in March: "Guy hasn’t put on a raps jersey the last 10 years, one good year, chucks it on."

Stephens had planned on starting her clay-court season at the Volvo Car Open in Charleston, but she withdrew from the tournament after winning the title in Miami.
