During the 2025-26 regular season the Thunder lost 18 games, four of those to San Antonio, giving the Spurs a 4-1 edge in head-to-head meetings. Oklahoma City’s depth—a ten-player rotation with a starter net rating of +11.3 per 100 possessions and reserves at +7—propelled them past the Phoenix Suns and Los Angeles Lakers. Coach Mark Daigneault, a former Coach of the Year, leads the Thunder, while Mitch Johnson, a Coach of the Year finalist, guides the Spurs. Individual honors include 2024-25 MVP Shai Gilgeous-Alexander (OKC) and 2025-26 Defensive Player of the Year Victor Wembanyama (SA).

Thunder guard Shai Gilgeous-Alexander averages 29.1 points, 7.1 assists and shoots 63.1 % true-shooting; Chet Holmgren contributes 18.6 points and 9.1 rebounds; rookie Ajay Mitchell adds 18.8 points, 4.9 assists and 4.0 rebounds. Nine Thunder players log at least 10 minutes per game, with three-point accuracy above 36 % for several role players. Spurs forward Victor Wembanyama posts 20.3 points, 10 rebounds, 4.1 blocks and shoots 53.8 % from the field; his on-court net rating is +118.3 points per 100 possessions, a 14.8-point swing compared with his bench time. Supporting cast includes Stephon Castle, Devin Vassell, Keldon Johnson and rookie Julian Champagnie, each offering perimeter defense and scoring.

Oklahoma City’s defense, the league’s No. 1 for a second straight season, allows 6.5 fewer points per 100 possessions than opponents, yet its offense has driven an 8-0 playoff start. The Spurs rank No. 1 defensively in the postseason, limiting opponents to 99.6 points per 100 possessions when Wembanyama is on the floor. Size matchups will be pivotal: the Thunder’s 7-foot-1 Holmgren and 7-foot-0 Hartenstein counter Wembanyama’s 7-foot-4 presence, while the Spurs’ perimeter unit—Castle, Vassell, Johnson—aims to disrupt Gilgeous-Alexander’s playmaking.

Analysts differ on the series outlook. Snellings argues the Spurs “match up very well” with the Thunder, citing their four-of-five regular-season success and Wembanyama’s paint control. Moody backs a Spurs +6.5-point opening-game line, emphasizing the team’s hunger against a two-time regular-season MVP. Conversely, Alexander predicts a sub-5.5-game total, suggesting the Thunder’s experience could render the series less competitive. These opposing views highlight uncertainty despite the statistical advantages each side holds.

ESPN

• “The Spurs famously won four of their five games with the Thunder this season, but that wasn't by accident.” — Snellings, ESPN betting analyst

ESPN

• “5 (-110) in Game 1: The Spurs dominated the Thunder in the regular season to the tune of a 4-1 record and Victor Wembanyama & Co.” — Moody, ESPN betting analyst

ESPN

• “5 (+130): Yes, the Spurs performed well versus the Thunder during the regular season, but this is a new season, and only one of these teams is experienced.” — Alexander, ESPN betting analyst

Game 1 kicks off in Oklahoma City on May 4 at 8:30 p.m. ET, with the series following a 2-2-1-1-1 format. If the Thunder sustain their offensive momentum, a sweep is plausible; however, a Spurs victory in any of the first three games would shift the series to a longer, more contested battle. The outcome will hinge on whether Wembanyama can replicate his regular-season dominance and whether the Thunder’s depth can neutralize San Antonio’s defensive schemes.
