The game was tied with 2 1/2 minutes remaining when Houston’s P.J. Tucker hit a 3-pointer from the corner. A layup by Rudy Gay got the Spurs within one with just under a minute left before Harden missed a 3 on the other end.
A 3-pointer by Bryn Forbes rolled on the rim before bouncing out, and Harden made two free throws to extend the lead to 109-106 with 16.2 seconds left.
Forbes missed another 3 with 10 seconds left, but the Spurs got the ball back when Clint Capela knocked the the ball out of bounds while fighting for a rebound. The Rockets then intentionally fouled two times, and Derrick White made a free throw before purposely missing the second one with 2.7 seconds left. But Westbrook grabbed the rebound to secure the win.
Houston fell behind early in a game where Harden had just nine points on 4-of-17 shooting in the first half. He warmed up after the break and finished 10 of 29.
“My confidence is never gone, no matter if I go 0 for 20 or whatever,” he said. “I’m always going to shoot the ball and be aggressive. Early my shot wasn’t falling … and then other guys stepped up.”
The Spurs managed just 35 points after setting a season high for first-half scoring. LaMarcus Aldridge led San Antonio with 19 points and 13 rebounds, and Forbes had 18 points.
“Some ways it’s like your worst nightmare to go up 20 quickly because you know the thing is going to turn to some degree,” San Antonio coach Gregg Popovich said. “So the way it was an even game down the stretch is pretty much what you’d expect most of the time.”
It was the first meeting between the teams since a 135-133 win by the Spurs in double overtime on Dec. 3 in which a dunk by Harden was wrongly disallowed, leading to a protest by the Rockets. Houston lost the protest, which would have resulted in part of the game being replayed. But the league said it disciplined the officials who got the call wrong and botched the aftermath by not allowing Houston to challenge the ruling.
The Rockets cut the lead to three on a dunk by Capela with about 10 minutes left before DeMar DeRozan scored four quick points to stretch it to 93-86.
A 13-4 run by Houston made it 99-97 with five minutes to go, lifting the Rockets to their first lead since 2-0. The Rockets got four points from Danuel House and a 3 from Harden in that stretch while the Spurs missed seven shots.
DeRozan tried to explain how things went so wrong for the Spurs after the break.
“They just picked it up,” he said. “We kind of slacked. It’s always hard playing with a lead. Every single quarter, you have to play even harder, because nobody wants to get embarrassed.”
The Spurs were up 72-53 at halftime.
