San Antonio Spurs vs. Oklahoma City Thunder, Picks and Prediction, Saturday, December 13, 2025
We're down to four teams in the NBA Cup with the second game on Saturday, this Spurs vs. Thunder prediction on Saturday at 9pmET from Loas Vgeas. San Antonio (17-7, 13-10-1 ATS) has managed to reach the NBA semifinal despite not having 7-foot-4 star forward Victor Wembanyama, who has been out for weeks with a calf injury. However, there is a chance that Wembanyama will play in this game. Oklahoma City is off to a 24-1 start (14-11 ATS), which matches the 2015-16 Golden State Warriors for the best 25-game start in NBA history. These teams have not met this season, and last year, the Thunder took two of three games, but covered just one of them. OKC is a 9-point favorite, and the total is 226.

Thunder are destroying teams
On Wednesday, OKC took on Phoenix in the quarterfinals of the NBA Cup and demolished them 138-89 as a 15.5-point favorite. It was the worst loss in Suns' history in terms of margin of defeat and a continuation of as dominating a performance as seen since the Warriors of 2015-16 of Steph Curry and Klay Thompson in their prime. Shai Gilgeous-Alexander went 11 for 15 from the field, scored 28 points, and dished out eight assists. Chet Holmgren added 24 points, eight rebounds, and three blocks for an OKC team that shot 59% from the field and 55% (22-of-40) from beyond the arc.
It just keeps getting better for Oklahoma City as Jalen Williams (6-5, 211) just made his season debut on Nov. 28 and has played in six games due to a right wrist injury. He's averaging 17.3 points, 6.3 assists, and 5.2 rebounds. This team not only defends (first in Adjusted Defensive Rating), but they also share the ball as they rank 11th in assists per game at 26.8. SGA leads the Thunder with 32.6 points per game, 6.5 assists, and shoots 56.2% from the field (45.4% 3pt). Holmgren adds 18.8 points, 8.0 rebounds, and 1.5 blocks, while shooting 58.1% from the field and 38.5% from long range. OKC is fifth in the league in three-point percentage at 38.1%.

Spread Pick for Spurs vs. Thunder
Spurs vs. Thunder Picks and Prediction
- San Antonio +9 (4 units)
Yes, the Thunder are humiliating teams right now, but Wemby playing now changes things. He just makes it more difficult for the Thunder to score down low and even if Holmgren pulls him away from the basket, he will be tough to shoot over. The Spurs had won four of their last five games without Wemby and players like Castle and Keldon Johnson were starting to jell along with Fox. All the strong first-round picks are starting to play-just like OKC. These teams, barring injuries, should be fighting for the top seed in the Western Conference for years to come. Take the points.
Over/Under Pick for Spurs vs. Thunder
- Over 225.5 (4 units)
These teams are about average when it comes to pace, but the Spurs have put up some big numbers lately without Wemby in the lineup. They've gone over in three straight and six of their last seven games. The Thunder have gone over in five of their last six games. They rank third in the league in field goal percentage at 50.1%, while the Spurs allow teams to shoot 48.7% from the field away from home
