James Harden scored 15 of his 29 points in the fourth quarter as the visiting Oklahoma City Thunder rallied for a 103-97 win Saturday night to sweep the defending NBA champion Dallas Mavericks out of the playoffs in four straight.

Oklahoma City finally took the lead, and kept it, after Russell Westbrook stole the ball from Dirk Nowitzki and passed to Serge Ibaka for a two-handed slam that made it 92-91 with 5:17 left.

Chris Paul had 24 points and 11 assists and high-flying Blake Griffin added 17 points for the Los Angeles Clippers, who beat the visiting Memphis Grizzles, 87-86, only after Rudy Gay missed a jumper just before the buzzer.

Paul hit a fadeaway jumper with 2:02 left for an 82-80 lead. On the next possession he had a no-look bounce pass to Griffin coming in off the baseline for a monster slam.

Trailing 86-80 after two free throws by Paul, Gay hit a three-pointer with 12.9 seconds left, Memphis' first field goal since 7:10. After Los Angeles missed three of four free throws, Gay hit another trey with 8.9 seconds.

Eric Bledsoe missed two more free throws, Gay got a good look but missed. Gay finished with 24 points.

George Hill hit a pair of free throws with 2.2 seconds left in overtime to help the Indiana Pacers survive squandering a 19-point fourth-quarter lead and beat the host Orlando Magic, 101-99, to take a 3-1 lead in the first-round series.

David West scored 26 points, including 12 in the third quarter and four in overtime for Indiana. Danny Granger added 21 points.

Andrew Bynum is promising to get to Denver's Pepsi Center early for Game 4 of Los Angeles' first-round series against the Nuggets following his first-half doughnut in a 99-84 Game 3 loss for the Lakers on Friday night.
