(AP) - Lonnie Walker IV had a career-high 28 points and the San Antonio Spurs overcame James Harden’s 50 by rallying from a late 10-point deficit to beat the Houston Rockets 135-133 in double overtime. Harden was whistled for two charges in the second overtime, including one with 0.8 seconds left. He was also robbed of a slam dunk by a botched call in the fourth quarter. Houston took too long to ask for a review, costing the Rockets two crucial points.
