LOS ANGELES -- Nothing was going to rattle the calm, cool and collected Spurs. Not even a 24-point deficit.

Tim Duncan scored 19 points, helping engineer a defining 24-0 run in the third quarter, and San Antonio defeated the Los Angeles Clippers, 96-86, Saturday to take a commanding 3-0 lead in their second-round playoff series.

"We didn't plan on being down that much," said Duncan, who at 36 is hungry to win the team's fifth NBA championship and first since 2006-07. "We stuck with it."

Led by Tony Parker's 23 points and his defense on an ailing Chris Paul, the Spurs kept running their plays even as Blake Griffin's early offensive assault buried them in a huge hole. Griffin missed three shots in the first half, when he scored 20 points and carried his team to a 24-point lead despite a left hip injury and sprained right knee.

"They came out like we expected, very strong. Blake was making crazy shots," Parker said. "We just took our time."

Griffin had 28 points and 16 rebounds, and reserve Mo Williams 19 points for the Clippers, who face some daunting NBA history heading into Game 4 Sunday at Staples Center. No team has ever rallied from a 3-0 deficit to win a series. The Spurs are 7-0 in the playoffs.

Thunder 103, Lakers 100: Russell Westbrook had 37 points, Kevin Durant 31 and Oklahoma City erased a 91-78 deficit in the final eight minutes in the nightcap at Staples Center.

Durant hit a three-pointer with 14 seconds left to give the Thunder a 101-98 lead. Kobe Bryant, who had 38 points, missed a three-point attempt with 8.9 seconds left. James Harden rebounded, was fouled and hit two free throws for a 103-98 lead with 7.3 seconds left.

Oklahoma City has a 3-1 lead in the series.
