Oklahoma City, OK (SportsNetwork.com) - Serge Ibaka sat on the Oklahoma City Thunder bench for the final few minutes of Game 3. It wasn't because he was hurt. Ibaka had 15 points, seven rebounds and four blocks and the Thunder defeated the San Antonio Spurs, 106-97, on Sunday night to get right back into the Western Conference finals. Ibaka was initially expected to miss the remainder of the season with a left calf strain he suffered against the Los Angeles Clippers on May 15, but his status was upgraded to day-to-day on Friday. Ibaka hit his first five shots from the floor and provided the defensive spark Oklahoma City had been lacking during the first two games of this set. Without Ibaka, the Thunder allowed the Spurs to shoot at least 50 percent in the first two tilts and San Antonio won them by a combined 52 points. The Spurs shot just 39.6 percent (36-of-91) from the floor in Game 3. OKC has been in this position before. It fell behind San Antonio 2-0 in the 2012 West Finals before rallying to win the next four games. Game 4 is Tuesday night in Oklahoma City. Russell Westbrook finished 8-of-19 from the field after missing seven of his first eight shots, netting 26 points to go with eight rebounds and seven assists. Durant added 25 points and 10 boards for the Thunder, who held a commanding 52-36 advantage on the glass. Manu Ginobili nailed six 3-pointers and scored 23 points for San Antonio, which has dropped eight straight to the Thunder in OKC, including the postseason.
