The Dallas Mavericks returned to San Antonio on Saturday night for a rematch with the Spurs, just two days after meeting them in Dallas. The venue changed but the outcome did not – San Antonio walked away with a decisive 138-125 victory, led by a dominant 40-point triple-double performance from guard Stephon Castle.

Why it matters

This game highlighted a defensive breakdown for the Mavericks, who struggled to contain Castle and the Spurs' offense. With multiple new players still integrating into the lineup, Dallas risks falling further behind in the standings unless they can tighten up their perimeter defense and accelerate the incorporation of newcomers like Marvin Bagley III.

The details

The Spurs surged ahead by ten points early and never looked back, despite a brief second quarter lead for the Mavericks. Castle scored 21 points in the first half and finished the game with 40 points, 12 rebounds and 12 assists, joining the Spurs' elite performers. The Mavericks debuted Tyus Jones, Marvin Bagley III and AJ Johnson, but struggled to find a rhythm, with Cooper Flagg posting a -31 rating and Max Christie a -23.

  • The Spurs led by 14 points at halftime.
  • By the third quarter, the Spurs' advantage had swelled to a 28-point lead with about four minutes left.
  • Castle sat out the final five minutes of the game after completing his 40-point triple-double.
