OKLAHOMA CITY - Kevin Durant scored 37 points, Russell Westbrook added 28, and the Oklahoma City Thunder beat the San Antonio Spurs 113-99 on Thursday night to win the Western Conference semifinal series 4-2.
Steven Adams had 15 points and 11 rebounds, and Andre Roberson added 14 points for the Thunder.
Oklahoma City lost 124-92 in Game 1, but first-year coach Billy Donovan led the Thunder to victory in four of the next five. Oklahoma City will face defending NBA champion Golden State in the Western Conference finals, starting Monday in Oakland.
And the Spurs could head into an uncertain future after a franchise-record, 67-win season, with 40-year-old Tim Duncan struggling for much of the series before scoring 19 points as San Antonio tried to fight back in the fourth quarter.
Kawhi Leonard scored 22 points and LaMarcus Aldridge added 18 for the Spurs. San Antonio lost just once at home during the regular season, but the Thunder beat the Spurs twice in San Antonio during the series.
It was a season-low point total for the Spurs in a first half. San Antonio shot 31.1 percent from the field before the break and missed all nine of its 3-pointers.
