SAN ANTONIO — James Harden had a slam dunk waved off by officials, the first sign that it might not be the Houston Rockets' night.
Lonnie Walker IV helped make sure of that.
Walker had a career-high 28 points and the San Antonio Spurs overcame Harden's 50 points by rallying from a late 10-point deficit to beat Houston 135-133 in double overtime Tuesday.
Harden played a season-high 49 minutes coming off a 60-point outing Saturday over three quarters against Atlanta, but he was whistled for two charges in the second overtime. The second came against DeMar DeRozan with 0.8 seconds remaining, sealing San Antonio's victory.
That followed a bizarre moment in the fourth quarter, when officials erased Harden's dunk with 7:53 remaining and Houston leading 102-89. Officials ruled the ball didn't clear the cylinder, but crew chief James Capers said after the game that, "in fact it did clear the net and should have been a successful field goal."
Capers said the Rockets did not ask for a review within the 30-second window that coaches can challenge calls, during which time they were arguing and asking for clarification. The botched call crushed Houston's momentum.
"We just stopped playing and they gained confidence," Harden said.
The Rockets led by 22 in the second half and were up by double digits in the fourth quarter for all but the final 4:18.
