The Pick: Spurs 117, Thunder 115

We’re taking the Over based on the head-to-head stats and Oklahoma City’s 2025-26 data paired with San Antonio’s trends on opening night.


Game Betting Analysis

The Over has the most conviction in the betting data, so we’ll go there, as the Over has hit in a remarkable 10 of 11 season opening games for the Spurs.The Over has also hit in six of eight meetings between the Thunder and Spurs, while the Thunder posted the sixth-most Overs in the NBA last season. The ATS and moneyline markets are a bit murky, as the head-to-head data suggests San Antonio winning and covering as it has done in eight of 12 meetings with the Thunder. Oklahoma City has, however, covered seven of nine season opening games while the Spurs lost their last three games at home from last year’s postseason.


Thunder-Spurs Odds (Spread, Moneyline, Over/Under)

Deciding Factor: Shai Gilgeous-Alexander’s MVP Burden vs. Victor Wembanyama’s Defensive Wall

Oklahoma City opens the season looking to avenge the gutting way last year ended, a 111-103 Game 7 road loss to San Antonio in the Western Conference Finals after the Thunder had gone 64-18 in the regular season. Shai Gilgeous-Alexander enters coming off his second straight MVP at 32.7 points per game, and he’s already proven he can get his against this specific opponent, averaging 29.5 points, 5.5 assists and 4.5 rebounds on 50.6 percent shooting across four meetings with the Spurs last season, including a 34-point outburst in a plus-29 blowout in January. The supporting cast looks different after Sam Presti shipped Lu Dort to Atlanta in a three-team, cap-driven trade, but Chet Holmgren, who missed the Thunder’s entire preseason with a quad issue, was cleared just a day out and is good to go for Tuesday’s opener. If Gilgeous-Alexander’s track record against this exact Spurs roster carries over and Holmgren’s conditioning holds up after missing all of training camp, Oklahoma City has the pieces to deliver an immediate measure of revenge.

San Antonio, meanwhile, is running it back off the best season of the Victor Wembanyama era, a 62-20 campaign that carried the franchise back to the NBA Finals for the first time since its 2014 championship run, before falling to the Knicks in five games after outlasting these same Thunder in that seven-game classic. Wembanyama was a unanimous Defensive Player of the Year last season, posting 25.0 points, 11.5 rebounds and a league-leading 197 blocks, the exact brand of interior deterrence that already flipped one series against Oklahoma City. The complication is depth: Tobias Harris (left calf) is questionable after missing the entire preseason, and Jayden Quaintance is out for the year with a torn ACL, thinning San Antonio’s wing rotation behind Devin Vassell and Julian Champagnie just as Mitch Johnson, now in his second season, tries to replicate last spring’s formula. If Wembanyama’s two-way dominance travels into opening night unaffected by those frontcourt absences, the Spurs have every reason to believe they can write the first chapter of this rematch in their favor.
