Spurs vs. Thunder Best Bets - Game 1
1. Dylan Harper – Over 10.5 Points (-120) Click here to get the best odds at DraftKings Sportsbook
- AI Probability: 80.25%
- Implied Probability: 54.65%
- EV: 46.86%
- Trend: Over in 7 of last 10
Harper has been one of the most consistent scoring angles on the board, clearing this line in 7 of his last 10. San Antonio will need secondary offense to keep pace with Oklahoma City, and Harper’s aggression gives him a clear path to double digits. This number is still low for his current role in a conference finals opener.
2. Stephon Castle – Over 5.5 Rebounds (+114) Click here to get the best odds at DraftKings Sportsbook
- AI Probability: 67.3%
- Implied Probability: 46.73%
- EV: 44.02%
- Trend: Over in 3 of last 10
The trend is not strong, but the price is. Castle’s size and activity give him rebounding upside in a matchup where Oklahoma City will force long misses and fast possessions. At plus money, The Wolf is buying the role and physical profile over the recent hit rate.
3. Chet Holmgren – Over 15.5 Points (-108) Click here to get the best odds at DraftKings Sportsbook
- AI Probability: 72.86%
- Implied Probability: 51.81%
- EV: 40.62%
- Trend: Over in 8 of last 10
Holmgren has been red hot as a scorer, clearing this line in 8 of his last 10. San Antonio’s defense will have to account for Oklahoma City’s guards, which should give Chet room to operate as a finisher and spacer. In Game 1 at home, his offensive role looks too strong to fade.
4. Jalen Williams – Over 4.5 Assists (+100) Click here to get the best odds at DraftKings Sportsbook
- AI Probability: 68.51%
- Implied Probability: 50%
- EV: 37.02%
- Trend: Over in 7 of last 10
Williams has become a key connector in Oklahoma City’s offense, clearing this assist line in 7 of his last 10. The Thunder do not need him to force scoring if the ball is moving, and his ability to attack, draw help and kick out fits this matchup well. At even money, this is one of the cleaner creation plays on the slate.
5. Cason Wallace – Over 2.5 Rebounds (+105) Click here to get the best odds at Caesars Sportsbook
- AI Probability: 63.93%
- Implied Probability: 48.78%
- EV: 31.06%
- Trend: Over in 4 of last 10
Wallace only needs three boards, and that is reachable if his minutes hold in the playoff rotation. Guard rebounds can spike in pace-heavy games, especially when long shots lead to loose-ball opportunities. The recent trend is modest, but the plus-money price makes this a sharp value play.
