Trailing by one with 6.1 seconds left, the Rockets got as good a look at the rim as they could get. James Harden was able to drive for what seemed like an easy layup. But then Tim Duncan happened.
No foul was called, much to the chagrin of the Rockets players, but this replay angle shows a clean block by Duncan:
The Spurs won their 10th straight game and, more importantly, moved into the third seed in the Western Conference.
