After building a 21-point lead, the Oklahoma City Thunder were overcome methodically by the visiting San Antonio Spurs to punctuate a 100-95 defeat.

On an anticlimactic night for Oklahoma City, Russell Westbrook (32 pts, 15 rebs, 12 ast) garnered triple-double #39, yet faltered (2-of-7 4Q) late.

Leading 69-51 midway through the third, Oklahoma City yielded a decisive 34-16 comeback to Gregg Popovich’s staid crew. This run evened the contest as 4:28 remained. With time elapsing, MVP-candidate Kawhi Leonard (28 pts, 8 reb) and All-Star veteran LaMarcus Alrdrige (14 pts, 10 reb) assured victory.

Oklahoma City’s second-half meltdown was due in large part to Steven Adams (5 fouls) and Andre Roberson’s (5 fouls) foul-issues, which prevented the pair from continuing to aggressively limit San Antonio’s prolific-frontcourt duo.

Largely unencumbered, in a total turnabout, San Antonio outscored OKC 52-26 with 18 minutes to play. This hegemony included a +8 rebounding margin as Oklahoma City (32/14/62 shooting, 6 TO, 10 PF) collapsed from the field.

The Thunder’s polarizing performance was starkly contrasted by each half. Billy Donovan’s men appeared too athletic and physical at the outset for San Antonio. However, the 58-win Spurs withstood their rival’s best to prevail with characteristic savvy.

Spurs reserve-standouts Pau Gasol (17) and Patty Mills (10) added double-figures for their title-contending iteration.

Meanwhile, Victor Oladipo (16), Steven Adams (13) and Enes Kanter (11) joined Russell Westbrook in twin-figure scoring for Oklahoma City.

With the loss Oklahoma City (43-32) is now 3-3 in its last six outings.

San Antonio (58-17) is closing in on a third 60-win campaign in four years.

The Thunder next face visiting Charlotte Sunday afternoon.
