The Biggest Upset of the Postseason

Game 1 of the Western Conference Finals became one of the biggest games of the postseason. The San Antonio Spurs walked into Chesapeake Energy Arena and walked out with a statement win, defeating the Oklahoma City Thunder 122-115 on the road.

This wasn't just a win — it was a declaration. The Spurs stole home court advantage by doing something many thought was impossible: beating the league's best team where they dominate.

Key Moments That Decided the Game

  • Wembanyama Dominated Late: The 7-footer altered shots, blocked layups, and turned away everything OKC tried in the paint down the stretch.
  • Stephon Castle Attacked Repeatedly: The young guard attacked OKC's perimeter defense over and over, getting to the rim at will and drawing crucial fouls.
  • Shai Scored Heavy Early, Struggled Late: The MVP front-runner started hot but the Spurs' defense locked in when it mattered most, forcing tough shots in the clutch.
  • Spurs Closed with Elite Defense: San Antonio finished the game on a 15-5 run, holding OKC to just 5 points in the final four minutes.

THE SPURS DON'T JUST BUILD TEAMS — THEY BUILD DYNASTIES. THIS IS THE BEGINNING.
