Redeem our Underdog promo code TOPACTION today and include these Spurs vs. Thunder predictions gathered from NBA staff writers in your qualifying entry:
- Stephon Castle Higher Than 16.5 Points: Castle has proven he can find a massive amount of success against this Thunder defense. He played really well against Oklahoma City this season, averaging 19.8 points per game over four of the five games they played. He also dropped 17 points in Game 1, carrying that success into the postseason.
- Alex Caruso Higher Than 15.5 Points, Rebounds, & Assists: Caruso saw an increase in minutes during the series opener. Caruso is built for these physical moments where you have to scrape and claw for timely buckets. He proved that in Game 1 by stuffing the box sheet with 34 combined points, rebounds, and assists.
- Ajay Mitchell Higher Than 9.5 Points: Mitchell had taken his game to a new level in the playoffs, 18.7 points throughout his first eight postseason games. Mitchell only scored four points in Game 1, but I think he's too talented to be kept down for long. The Thunder need his scoring to keep pace with the depth of the Spurs.
