Spurs Seek Turnaround as Stephon Castle’s Turnovers Become Major Concern

The San Antonio Spurs left Oklahoma City with the Western Conference Finals tied at one game apiece, but Game 2 exposed a growing concern that could shape the remainder of the series. While the Spurs continued to show resilience against the defending champions, repeated turnovers proved costly in their 122-113 loss to the Thunder on Wednesday night.

At the center of the issue was sophomore guard Stephon Castle, who has taken on a significantly larger offensive role due to injuries in San Antonio’s backcourt. Castle once again delivered impressive scoring numbers and flashes of star potential, but Oklahoma City consistently disrupted his decision-making with relentless defensive pressure.

Following the loss, interim head coach Mitch Johnson openly addressed the problem while continuing to defend one of the franchise’s most important young players. Johnson acknowledged that Castle’s turnovers have become an issue, particularly as fatigue and defensive attention continue to increase during the series.

Despite the mistakes, San Antonio remains encouraged by Castle’s overall growth and competitiveness. The Spurs now return home understanding that if they want to regain control of the series, improving ball security will become just as important as containing Oklahoma City’s explosive offense.

1. Castle Faces Heavy Pressure in Expanded Role

Castle entered the Western Conference Finals already carrying major responsibilities, but injuries have forced him into an even larger role than expected. With All-Star guard De’Aaron Fox sidelined because of ankle soreness and Dylan Harper leaving Game 2 early with a leg injury, San Antonio relied heavily on the 21-year-old to organize the offense. That workload has come with growing challenges against Oklahoma City’s aggressive defense. Through the first two games of the series, Castle committed 20 total turnovers, including 11 in Game 1 and nine more in Wednesday’s loss. The total established an unwanted conference finals record and highlighted the difficulty of handling constant defensive pressure from the Thunder. Oklahoma City repeatedly trapped Castle near the perimeter, forcing rushed decisions and limiting clean passing lanes. The Thunder’s athletic defenders pressured him throughout the game, especially during stretches when San Antonio struggled to slow the pace or establish consistent half-court offense. Even so, Castle continued attacking offensively despite the mistakes. Rather than retreating after turnovers, he remained aggressive driving into the paint and creating scoring opportunities for himself and teammates. That confidence has become one of the defining characteristics of his rapid development this season.

2. Johnson Supports Young Guard Despite Mistakes

After the game, Johnson addressed Castle’s struggles directly while emphasizing that the responsibility extended beyond one player. The Spurs coach acknowledged the turnovers but also pointed to the collective issues San Antonio faced against Oklahoma City’s defensive intensity. Johnson specifically mentioned fatigue as one factor impacting Castle’s decision-making. Because of injuries, the young guard has been asked to play heavy minutes while handling primary playmaking duties against one of the league’s deepest defensive teams. Those demands have increased both the physical and mental pressure on the sophomore guard. Importantly, Johnson avoided placing blame solely on Castle. The coach stressed that the entire team contributed to San Antonio’s turnover problems, reinforcing the organization’s continued confidence in the young backcourt leader despite the difficult stretch. That support reflects how highly the Spurs value Castle’s long-term potential. Throughout the postseason, he has consistently demonstrated maturity and resilience, responding to setbacks with aggressive play rather than hesitation. The organization appears committed to allowing him to grow through the challenges of playoff basketball rather than limiting his responsibilities.

3. Spurs Still Show Signs of Promise

Although the turnovers overshadowed much of the conversation after Game 2, Castle still delivered an impressive statistical performance. He led San Antonio with 25 points on efficient 10-of-17 shooting while also contributing eight assists and five rebounds in 38 demanding minutes. Victor Wembanyama also remained productive despite Oklahoma City focusing significant defensive attention on him. The Spurs superstar recorded 21 points, 17 rebounds, and four blocks, continuing to impact the game on both ends of the floor even when his offensive rhythm fluctuated. Ultimately, Oklahoma City capitalized on San Antonio’s mistakes more effectively than the Spurs could recover from them. The Thunder finished with a commanding 27-10 advantage in points off turnovers, a margin that played a major role in determining the outcome. Shai Gilgeous-Alexander’s 30-point performance further punished every Spurs mistake during the second half. Now tied 1-1, the series shifts to Frost Bank Center for the next two games. San Antonio hopes the home environment can help stabilize its young roster, but the Spurs also understand that reducing turnovers will likely determine whether they can reclaim momentum against the defending champions.
