SAN ANTONIO (AP) - Tim Duncan scored 27 points and the San Antonio Spurs took advantage of Serge Ibaka's absence to dominate the paint, beating the Oklahoma City Thunder 122-105 on Monday night in the opener of the Western Conference finals.
Manu Ginobili added 18 points and Kawhi Leonard and Danny Green had 16 points each. Tony Parker did not appear limited by a hamstring injury, posting 14 points and 12 asssists.
Kevin Durant scored 28 points and Russell Westbrook added 25. Oklahoma City's remaining starters, Nick Collison, Thabo Sefolosha and Kendrick Perkins combined to score five points.
The Thunder struggled without the defensive presence of Ibaka, who will miss the remainder of the postseason after suffering a calf injury in the Thunder's series clincher against the Los Angeles Clippers.
San Antonio had 66 points in the paint and shot 58 percent from the field.
The Spurs fed Duncan early with Ibaka out, and the veteran responded by scoring 12 points in the first quarter, making six of his seven shots.
The Spurs beat the Thunder for the first time this season.
