OKLAHOMA CITY — The San Antonio Spurs are back in the NBA Finals, beating the Oklahoma City Thunder 112-107 in overtime on Saturday night in Game 6 to set up a rematch with the Miami Heat.
Tim Duncan had 19 points and 15 rebounds for the Spurs, who will host Game 1 on Thursday night as they try to avenge last year's heartbreaking seven-game loss.
Boris Diaw scored 26 points for the Spurs, who won despite point guard Tony Parker missing the entire second half and overtime with left ankle soreness.
Russell Westbrook had 34 points, eight assists, seven rebounds and six steals, and Kevin Durant added 31 points and 14 rebounds for the Thunder. Oklahoma City overcame a 12-point deficit in the fourth quarter to force overtime.
Kawhi Leonard added 17 points and 11 rebounds, and Manu Ginobili chipped in 15 points and six rebounds for the Spurs, who pulled this one out after losing in overtime in Game 6 against the Heat in the NBA Finals.
San Antonio went on to drop Game 7, but put that loss behind and had the NBA's best record this season.
"It's unbelievable to regain that focus after that devastating loss we had last year," Duncan said.
In overtime, Duncan's shot from the baseline rattled in to give the Spurs a 110-107 lead with 19 seconds to go.
Durant missed a good look at a 3-pointer, and the Spurs rebounded and went to the line. Diaw missed the first and made the second free throw to make it a four-point lead for the Spurs. Westbrook missed a wild 3-pointer, and Spurs wrapped it up.
San Antonio led by 12 early in the fourth quarter, but the Thunder chipped away at the free throw line after getting the Spurs into foul trouble. Back-to-back baskets by Westbrook and Durant cut San Antonio's lead to 93-91 with 4:01 to play, leading to the frantic final minutes.
Durant made two free throws to tie the score at 97 with 58 seconds left. San Antonio attacked, but Serge Ibaka blocked Ginobili's shot at the rim — replays showed the ball hit the backboard first and should have been a goaltend — and Derek Fisher rebounded.
Durant quickly attacked the hoop out of a timeout and made a layup with 32 seconds to play, finally giving the Thunder the lead at 99-97.
Ginobili came back with a 3-pointer with 27 seconds to play, putting the Spurs back up 100-99.
