Thunder vs. Spurs Odds and Prediction
| Market | Thunder | Spurs |
|---|---|---|
| Moneyline | +110 | -130 |

| Total | Over 224.5 (-110) | Under 224.5 (-110) |
Thunder vs. Spurs Game 4 should come down to Oklahoma City’s perimeter shot creation against San Antonio’s interior advantage with Victor Wembanyama. The Thunder have the cleaner late-game offense behind Shai Gilgeous-Alexander, but the Spurs can swing the matchup if Wembanyama controls the glass and protects the rim.
Thunder vs. Spurs Prediction: Thunder moneyline (+110) Oklahoma City’s depth and half-court scoring give it the slight edge, though this projects as a competitive Western Conference Finals matchup.
