Isaiah Thomas scored 23 points and Evan Turner added 17 as the Boston Celtics beat the Toronto Raptors 91-79 Wednesday night at TD Garden, the team's first win against the division-leading Raptors this season.

It was Thomas' 11th straight game with 20 points or more. He was one of four Celtics to reach double digits in scoring as the team secured its first winning season under coach Brad Stevens.

DeMar DeRozan scored 21 points for the Raptors, who were without Kyle Lowry. The all-star point guard sat out Wednesday night's game with a sore elbow.

The Celtics remain in a tie with the Atlanta Hawks for the fourth seed in the Eastern Conference. Toronto is the conference's No. 2 seed and has a seven game lead on the Celtics in the Atlantic Division.

The Celtics, who will begin a five-game West Coast road trip Saturday in Phoenix, may get Jae Crowder back at some point during the road trip. Crowder has missed the last six games with a sprained right ankle.

"He shot pregame today. But from what I've been told, I don't think there's any movement shooting. I think it's just spot shooting," Stevens said before Wednesday night's game. "So no real update. He's going to go on our trip and, again, I said this the other day, I don’t want to put a timeline on him, but I don't anticipate him playing early in the trip."
