What if someone told you before tip-off Wednesday night that Russell Westbrook and Kevin Durant would combine for 30 points on 39 shots against the streaking San Antonio Spurs?

What if you knew that Westbrook would account for only six of those points and miss 14 of his 16 shot attempts?

“Would you have told me we would have won?” asked Thunder coach Scott Brooks.

Probably not.

Yet the Thunder found a way to get it done, passing its toughest test to date with flying colors and securing an remarkable 94-88 victory in a highly-anticipated showdown of two of the Western Conference's top teams.

With the win, the Thunder remained unbeaten at home, where it is now 7-0, while also snapping San Antonio's league-best 11-game winning streak.

Oklahoma City overcame a horrid offensive night from Westbrook and an uncharacteristically inefficient outing from Durant, who scored 24 points on 23 shots.

The Thunder did it behind a terrific bench effort, one that outscored a potent Spurs second unit, 39-37.

Reggie Jackson led the charge, tying his career high with 23 points on 10 of 14 shooting. He scored 14 of his points in the second half.

Second-year shooting guard Jeremy Lamb added 12 points, making five of seven shots in 20 minutes.

Serge Ibaka chipped in 17 points, 11 rebounds and five blocked shots, good for his team-leading sixth double-double.

Another phenomenal defensive effort by the Thunder was as critical as anything.

OKC held San Antonio to 39.1 percent shooting and limited a dangerous perimeter-shooting team to a 7-for-27 night from beyond the arc.

In the decisive second half, the Thunder held the Spurs to 42 points on 36.4 percent shooting.

“The way they score, they're a hard team to guard,” Brooks said. “And I thought our guys did a very good job with our length and making them miss some shots.”

San Antonio took a 46-43 lead into halftime despite some early shooting struggles. The Spurs missed 12 of 16 3-pointers in the opening half, including 10 of 11 in the first quarter.
