BOSTON -- Kevin Garnett had 24 points and nine rebounds as the Boston Celtics manhandled the Memphis Grizzlies, 98-80.

Paul Pierce added 21 points while Ray Allen and Chris Wilcox each netted 12 as the Celtics won their fourth straight game and remained perfect in a five-game homestand.

Rudy Gay had 21 points and seven rebounds to pace Memphis, which wrapped up a three-game road trip with a 1-2 record by dropping its last two contests.

After an 8-2 spurt by the Grizzlies put them up, 12-6, in the first quarter, the Celtics reeled off 10 straight points to jump ahead and held a 24-16 lead after the opening frame.

Memphis then came out hot in the second, opening the quarter with a 16-3 run that included five consecutive Boston turnovers and eight points by O.J. Mayo to take a 32-27 lead with less than seven minutes to go in the half.

The Celtics, though, responded with their own 16-3 swing to close out the half and owned a 43-35 advantage at the break.

Neither team shot well from long distance in the first half, as Memphis went 1-for-7 from three-point range and Boston connected on 1-of-10 shots from beyond the arc. Both teams also had 10 turnovers apiece in the first 24 minutes.

But Boston found its three-point stroke in the third quarter, converting on 5- of-8 shots from long distance -- three from Allen -- as the Celtics led by no less than five points and by as many as 12 en route to a 69-61 lead at the end of three quarters.

The game was never in doubt in the fourth, with Boston leading by double digits for the majority of the quarter.

HEAT 95, RAPTORS 89

LeBron James scored 30 points and Dwyane Wade had 25 as Miami survived a shaky fourth quarter to beat Toronto.

Chris Bosh scored 12 points against his former team, which saw a 15-point edge trimmed to three in the final minutes but never surrendered the lead. Mario Chalmers added 11 for Miami.

DeMar DeRozan scored 25 for the Raptors, who got 17 apiece from Jerryd Bayless and Linas Kleiza.
