Given another chance, he connected on a three to make it 90-86 with 17 seconds to play. The Grizzlies hung on to win for the fourth time in five games and snap the Thunder's six-game winning streak.
Oklahoma City had pulled within a game of league-leading Chicago by blowing out the Bulls a day earlier, but the Grizzlies took the lead just after halftime and never gave it back.
Memphis won despite playing without starting point guard Mike Conley (sore right ankle) and reserve Dante Cunningham (sprained left ankle) for the second straight game.
"We're missing a couple guys that are big for us but we've got to keep playing," said center Marc Gasol, who had 13 points and eight rebounds. "We're a no-excuse team. We've got to play. We've got to do what we've got to do."
It was the latest chapter in a budding rivalry created by last year's epic seven-game Western Conference semifinal series - including a triple-overtime game and one with a single overtime. Oklahoma City won Game 7 on its home court and had won all three previous meetings this season by a total of 15 points.
"It's always like this," Kevin Durant said. "This is our fourth time playing these guys. It's tough to beat a team four times in a row. They came out and made plays and you've got to give credit to those guys. They played hard."
