Thunder at Spurs Predictions, Odds and Betting Picks for Today
Jesse M. Cox Published 21/05/2026
Game 3 comes down to health in the backcourt. Jalen Williams left Game 2 with another hamstring issue, forcing Oklahoma City Thunder to lean even more on Shai Gilgeous-Alexander, who posted 30 points and 10 assists in the 122-113 win. The San Antonio Spurs also has key injury concerns with Dylan Harper out and De'Aaron Fox missing Game 2 due to ankle soreness.
The total at 215.5 stands out after back-to-back high-scoring games. The first two matchups produced 237 and 235 total points, while Victor Wembanyama has averaged 31.0 points and 20.5 rebounds in the series. Both teams also rank top five in playoff pace during the conference finals.
Best Bets for Thunder vs Spurs
- Player Prop: Victor Wembanyama Over 29.5 Points (-115 at DraftKings). Wembanyama has scored 41 and 21 points in the first two games on 23 shots per game. Oklahoma City has also fouled him into 18 free throws across the series.
- Game Total: Over 215.5 (-110 at FanDuel). The first two games averaged 236 total points with both teams scoring in transition off turnovers. Oklahoma City had 57 bench points in Game 2, while San Antonio is averaging 117.5 points per game in the series.
- Spread: Spurs -1.5 (-108 at BetMGM). San Antonio is 6-1 at home this postseason and has a +9 rebounding edge in this series. If Jalen Williams is out, Oklahoma City loses its second-best scorer and shot creator.
Thunder vs Spurs Game Preview
Oklahoma City responded in Game 2 with Shai Gilgeous-Alexander scoring 30 points. The Thunder added 27 points off turnovers and 57 bench points, which helped cover for Chet Holmgren's 13-point outing. San Antonio still got a big game from Victor Wembanyama with 21 points, 17 rebounds, and four blocks. Stephon Castle scored 25 points, but OKC pulled away with an 11-0 fourth-quarter run.

Injuries are key in Game 3. Jalen Williams is questionable with a hamstring issue, while De'Aaron Fox and Dylan Harper are both banged up. San Antonio returns home after covering five of its last seven playoff games.
Moneyline Pick
The Spurs are the moneyline pick in Game 3. They are winning the rebounding battle 53.0 to 40.5 per game, and that edge grows if Jalen Williams is limited or out again.
Victor Wembanyama is controlling the paint in Game 2 on both ends, dominating the interior with his presence and impact. Oklahoma City still leans heavily on Shai Gilgeous-Alexander, and the Thunder may struggle for scoring depth on the road without Williams at full strength.
Pick: Spurs ML (-120 at DraftKings).
Spread Pick
Spurs -1.5 is the strongest spread angle. San Antonio has won five of seven matchups and is slowing OKC down in half-court situations late. They are also 6-1 at Frost Bank Center this postseason. That level of bench scoring won't be easy to replicate on the road against a defense anchored by Wembanyama.
Pick: Spurs -1.5 - (-108 at BetMGM).
Best Player Props
- Victor Wembanyama: Over 29.5 Points - (-115 at DraftKings). Wembanyama is putting up 31.0 points in the series and continues to attack Holmgren inside. Oklahoma City has not found an answer for his length near the rim.
- Shai Gilgeous-Alexander: Over 8.5 Assists - (+105 at FanDuel). Gilgeous-Alexander is averaging 10.5 assists in the series while handling nearly every late-clock possession. If Williams is limited, the ball stays in his hands even more.
- Stephon Castle: Over 18.5 Points - (-110 at Caesars Sportsbook). Castle scored 25 in Game 2 and stayed aggressive attacking downhill. OKC's perimeter defense also dropped off after Williams exited the rotation.
- Chet Holmgren: Under 16.5 Points - (-112 at BetRivers). Holmgren scored just 13 points in Game 2 and has struggled against San Antonio's physical frontcourt. Wembanyama's rim protection is pushing him more to the perimeter.
Same Game Parlay for Thunder vs Spurs
This parlay leans into San Antonio winning a physical, high-usage game while Wembanyama continues to dominate scoring volume. OKC's reliance on Gilgeous-Alexander also keeps his production steady even in a loss script.
- Leg 1: Spurs Moneyline. Home court and rebounding edge drive the result.
- Leg 2: Victor Wembanyama Over 29.5 Points. Volume and mismatch scoring remain intact.
- Leg 3: Over 215.5 Total Points. Both prior games cleared this comfortably.
- Leg 4: Shai Gilgeous-Alexander 25+ Points. High usage ensures scoring stability.
Game Total Pick
The Over 215.5 still looks strong after both games finished at 237 and 235 total points. Oklahoma City scored 27 points off turnovers in Game 2. San Antonio keeps leaning on Victor Wembanyama and Stephon Castle for offense.
Fatigue also points to more scoring. The Thunder rotation is thinner after Jalen Williams' injury, and Wembanyama logged 43 minutes in Game 1. Both teams are averaging over 117 points in the series, keeping this total low.
Pick: Over 215.5 - (-110 at FanDuel).
