San Antonio coach Gregg Popovich thought Serge Ibaka's defense was the biggest problem the Spurs had in Game 3. On Saturday, Popovich and the Spurs saw how much of a headache the Thunder can be when Ibaka has a hot hand at the other end. Ibaka scored a playoff career-high 26 points to help the Thunder even the Western Conference Finals at two games apiece with a 109-103 win in Game 4 inside Chesapeake Energy Arena. Ibaka finished 11-for-11 from the floor. The NBA record for the most shots made without a miss in a playoff game is 12-for-12, set by Larry McNeill in 1975. Scott Wedman is the only other player in NBA history to go 11-for-11. He did it in 1985. “That's a pretty big effect,” a still astonished Popovich said. “All the (Thunder's) bigs really scored tonight. Obviously, you put most of your attention on the big three there and try to do a great job on them first. But the bigs came through tonight and were outstanding.” The Thunder's big man trio of Ibaka, Kendrick Perkins and Nick Collison combined to shoot 22-for-25. Perkins was 7-for-9. Collison was 4-for-5. “If you did a shooting drill with nobody guarding you, I don't think you could do that,” Popovich said. Ibaka scored just two points in the first quarter, laying in a feed from point guard Russell Westbrook. Ibaka, the league's leading shot blocker, started rolling in quarter two. The first two minutes of the second period became the tell-all sign that Ibaka would be in for a big night. He hit 18-footers on two of the Thunder's first four possessions. Previously in this series, Ibaka had struggled to knock down that shot, which had improved so much in his third season. Entering Game 4, Ibaka was just 9-for-23 from the field. “It's a great impact,” said Westbrook of Ibaka hitting midrange shots. “Serge continuously knocked those shots down in the first three quarters. Then, when it was time for Kevin (Durant) to (isolate) and give us what he needs, he has a lot of space. That just shows the commitment that we're making the right play and it worked for us.” Ibaka finished with 12 points in the second period, making all five of his shots. In the third quarter, Ibaka scored eight points on 3-for-3 shooting. He needed just four points, on 2-for-2 shooting, in the final period thanks to Durant's 18-point barrage, which included 16 straight to carry the Thunder across the finish line. “Eleven-for-eleven in Game 4 of the conference finals is not easy to do,” said Spurs guard Manu Ginobili. “I understand if he runs the floor for transition dunks or (scores) on drop-offs when we help. That can happen. But he made five to six jumpers, and that's something we were willing to give up. But he was impressive today.” Ibaka benefited from unselfish ball movement that saw the Thunder tie its season high of 27 assists. With each shot that swished through the net, Ibaka grew more and more confident. “After making my (first two) shots I was like, ‘OK, I'll just keep going,’ ” Ibaka said. “Every time I was open they kept passing to me and I shot the ball.” And never missed.
