NBA Prop Bets: Thunder vs. Spurs Game 3 Best Bets for Friday 5/22/26

The Western Conference Finals shift to San Antonio on Friday night, where the Spurs host the Thunder in Game 3 at the Frost Bank Center. The two teams split the first two games of the series in OKC, and Game 3 should be a great matchup to see which team will seize the 2-1 advantage. In what should be another awesome atmosphere with plenty of intensity, let’s take a look at my Thunder vs. Spurs best bets for Game 3 on DraftKings Sportsbook.

Overall, the Spurs are slight 1.5-point home favorites with the total set at 217.5 points. On the injury report, De’Aaron Fox (ankle), Dylan Harper (adductor) and Jalen Williams (hamstring) are all questionable, which makes things a little uncertain. However, from the players we know will play, a few strong player prop bets stand out.

Thunder vs. Spurs Props on DraftKings Sportsbook

Victor Wembanyama 15+ Rebounds (-104)

Wemby averaged 11.6 rebounds per game during the regular season, but he has been playing more minutes and doing more work on the glass during the postseason. Getting him to pull in at least 15 boards at almost even money is a strong place to start your Spurs-Thunder player prop bets for Game 3.

He had an impressive 24 rebounds in 49 minutes in Game 1, and followed that up with 17 rebounds in 37 minutes in Game 2. In the playoffs, he has played 31 minutes per game with an average of 12.3 rebounds per game, but several of those contests were blowout wins, and one was a game he left early after only 12 minutes due to a concussion.

If this game stays close throughout, as the first two games did in OKC, look for Wemby to carry the load for San Antonio down low and pull in at least 15 boards.

Cason Wallace Over 7.5 Points (-115)

Wallace is a key contributor on the defensive end for the Thunder and typically plays significant minutes. If Williams is out, he can help pick up the scoring, but even if Williams plays through his hamstring issue, Wallace should still get enough chances to go over this low scoring prop.

In the playoffs, Wallace is averaging 7.8 points per game after scoring 8.6 points per game during the regular season. He has gone over this prop line in five of his last seven contests, including each of the two games in this series. He had eight points in Game 1 and 12 points in Game 2.

Wallace had 13 points in his most recent regular-season game in San Antonio, and he could be a bigger part of the offense depending on Williams’ availability. Whether Williams plays or not, I like the over on this attainable scoring line for Wallace on the road.

Stephon Castle Over 32.5 Points + Rebounds + Assists (-110)

Castle has come to play in the first two games of this series, stepping up with 34 PRA in Game 1 and 38 PRA in Game 2. He has taken on more of the play-making responsibility in the absence of De’Aaron Fox, but even if Fox returns, using this combo instead of just a straight assists pick is a good way to get a little insurance.

Castle had 30+ PRA in three of his five meetings with the Spurs during the regular season and In-Season Tournament, but like Wemby, his minutes and numbers are both up so far in this series.

If Fox is back, Castle will likely have fewer assists, but he should get more scoring and rebounding chances. If Fox stays out another game, Castle will carry more of the load and is an even stronger play to get over this PRA line for a third straight game.

Bonus Parlay Play: Ajay Mitchell Under 3.5 Rebounds (-106)

If you are assembling a Same Game Parlay (SGP), be sure to take advantage of the Profit Boost to use on a 3+ leg parlay on DraftKings Sportbook. Adding in the under on Mitchell’s rebounds boosts the SGP odds to an even +1100 for the four Thunder-Spurs prop bets in this post.

Mitchell played 28 minutes in Game 2 and didn’t have a single rebound, and has been under this prop in four of his last six contests dating back to the series with the Lakers. Even if he gets more work with Williams out, that won’t necessarily mean he does more work on the glass. He did get more rebounds in the Suns series due to the matchup, and he isn’t unwilling to get boards, but it’s just not usually what he’s called on to do.
