OKC vs SAS Regular-Season H2H Results

The Spurs owned the season series against Oklahoma City, winning four of five meetings. Perhaps more importantly for bettors, San Antonio was a dominant 4-1 against the spread and the Under went 4-1 in these matchups.

The ATS data is particularly revealing. The Spurs covered as underdogs of 6.5 to 9.5 points in three of their four wins – outright victories where the market severely underestimated San Antonio’s ability to match up with Oklahoma City. The lone Thunder cover (Jan 13) was OKC’s only convincing win, a 21-point blowout.

Victor Wembanyama played in all five games against OKC, averaging 18.4 PPG, 9;.2 RPG, 2.0 APG, 1.2 BPG in just 25.1 minutes. He had a 52.4 FG% and an absurd 62.5 3P% (5-of-8).

SGA played in four of the five regular-season games against the Spurs, averaging 29.5 PPG, 4.5 RPG, 5.5 APG, and a 50.6 FG% in 35.5 minutes. He connected on just four of this 21 three-point attempts (19%).

Spurs vs Thunder Playoff Statistical Comparison

OKC’s numbers are staggering. An undefeated 8-0 playoff record with an Offensive Rating of 124.3 is historically elite. They’re shooting over 51% from the field and 38.4% from three while maintaining a +17.6 net rating.

However, San Antonio brings the postseason’s top-ranked defense (99.7 Defensive Rating), anchored by Wembanyama’s league-leading 7.7 blocks per game. The Spurs have allowed just 101.8 points per game—the fewest among remaining teams. This is the classic irresistible force vs. immovable object matchup.

OKC vs San Antonio Series Prediction

Oklahoma City’s undefeated playoff record and home-court advantage justify their status as series favorites. But the market may be overcorrecting. The Spurs won four of five regular-season meetings, covered four of five spreads, and boast the postseason’s top-ranked defense – the exact type of defense that can disrupt OKC’s rhythm.

Four of five regular-season meetings went Under, and San Antonio’s 99.7 Defensive Rating in the playoffs suggests they have the personnel to slow down even a historically efficient Thunder offense. Wembanyama’s rim protection fundamentally changes OKC’s ability to generate easy looks at the basket.

At +223, the Spurs offer legitimate upset value. They’ve proven they can beat this team, they have the best defensive player in the league, and they enter with significant playoff momentum after closing out Minnesota in six.

While OKC’s depth, championship pedigree, and home-court edge make them the rightful favorite, don’t be surprised if San Antonio’s defensive identity makes this a longer, more competitive series than the odds suggest.
