Durant was 10 of 23 from the field, including 3 of 5 from behind the arc, and 6 of 8 from the free throw line. He had nine rebounds and three assists.
Most of Durant's much-needed output came in the second half after the Spurs scorched the Thunder with 22 transition points in the first two quarters.
"We just had a lack of energy," he said. "The second half everybody was helping each other out, playing harder. Tony Parker broke us down a little bit early on. Our defense wasn't as tight as it should have been, but in the second half we did a great job of closing it up."
