The final NBA game for Wednesday will be between the San Antonio Spurs and the Golden State Warriors. Here are five of the best player props for the matchup on Underdog Fantasy.

Stephon Castle Over 12.5 Rebounds+Assists

Guard for the Spurs, Stephon Castle, has been filling up the stat sheet all year when it comes to generating rebounds and assists. In his last five games, he has covered the over on his 12.5 rebounds+assists line for Wednesday night four times. The following high hit rate should remain against the Warriors.

In two out of three games against Golden State this season, Castle has covered the over on his 12.5 line. This includes a game where he logged 10 rebounds and 10 assists.

Victor Wembanyama Over 25.5 Points

The next face of the NBA could very well be center for the Spurs, Victor Wembanyama. He has been a dominant player night in and out for San Antonio in the 2025-2026 season, and as of late, he has been scoring at a massive scale. 

In Wembanyama’s last four games, he has covered the over on his 25.5 point prop line for Wednesday every single time. This includes his latest game, where the Spurs took on the Chicago Bulls, and he scored 41 points. In his last two games against the Warriors this season, he has covered the over on the point prop line for Wednesday. The combo of his recent success in covering the over on the prop and his success against the Warriors makes his over on his points a great prop to take in this matchup.

Will Richard Under 9.5 Points

Wing for the Warriors, Will Richard, is having a solid rookie season. But against the Spurs on Wednesday night, he should struggle to generate points.

In Richards's last four games, he has had 10 or more points just one time. He takes the following scoring trend into a matchup against one of the best defensive teams in the NBA. The Spurs this season are allowing the eighth fewest points per game in the league, 111.4. In their last three games, they are allowing just 102.3 PPG. 

Draymond Green Under 5.5 Rebounds

In Draymond Green’s last three games, he has had fewer than six rebounds every single time. Going up against Wembanyama and San Antonio, that trend should carry on into Wednesday.

The Spurs this season are allowing the ninth fewest rebounds per game in the NBA. In their last three games, they are allowing just 44.0 RPG. The Spurs' strength on the glass alone recently is enough to warrant taking Green’s under on his 5.5 rebounding player prop.

Devin Vassell Over 2.5 Made 3-Pointers

In two of his last three games, Spurs wing Devin Vassell has made four or more threes. Going up against the Warriors, he should be able to generate at least three makes behind the arc.

Golden State has been good at limiting made 3-pointers this season. On average, they are allowing 12.8 per game—the 11th lowest average in the NBA. However, over their last three games, Golden State has allowed 16.3 makes, tied for the second-highest in the league over that stretch. With their recent struggles in defending the perimeter, Vassell should be able to take advantage of this and have a good shooting day from distance.
