The San Antonio Spurs preserved their unbeaten away record this season as they beat the Boston Celtics 109-103 at TD Garden to move to 13-3.
David Lee, Patty Mills and Davis Bertans were big off the pine for the Spurs as Kawhi Leonard led the five-time champions with 25 points and 10 rebounds.
Boston dropped their third home game of the campaign and now hold a 9-7 record. Isaiah Thomas' 24 points and eight assists were not enough to extend their three-game winning streak.
The home team raced into an early lead and were up by 14 at one point. The Spurs gave up 32 points in the first quarter as they trailed by 10 after the opening 12, with Jae Crowder dropping 10.
San Antonio rallied in the second, going into the half down by two off the back of a strong showing from Bertans, who had nine. Leonard was up to 10 by the interval.
The Western Conference powerhouse led by one point as the final quarter commenced thanks to a deep buzzer-beating three by Mills. Latvian Bertans had a career-high 12 points after three quarters.
The game went back and forth with the Spurs stretching their lead to five. However, a three-point play from Marcus Smart had the score at 84-86 to Gregg Popovich's men. Smart missed a golden opportunity to put the Celtics within two as he missed a wide-open shot from up close after some great ball movement from Boston left him open.
Leonard put the Spurs up by eight with 1:39 left with two decisive free throws after a foul from Horford - his third of the game.
After a Thomas lay-up and three pulled the Beantown franchise back to within three, San Antonio ran a perfect play that resulted in Mills nailing an open three of his own.
LaMarcus Aldridge came up with a huge rebound off a Manu Ginobili miss to put the game beyond Boston as the Celtics resorted to fouling with only 17 seconds to go. The former Portland big man hit both shots at the line, and that was all she wrote.
The Spurs' bench was a deciding factor as Lee ended with season-high 15 while Bertans had a career-high 15. Mills also had 19.
