Stephon Castle gave NBA fans another reason to believe the San Antonio Spurs are becoming one of the league’s most entertaining teams. His emphatic alley-oop dunk over Sacramento Kings center Dylan Cardwell, set up by a perfectly timed lob from Victor Wembanyama, was one of the highlights of San Antonio’s 124-109 victory on Friday night. The play had everything: Wembanyama’s vision, Castle’s explosive finish and a defender left with little chance of stopping the action. It also provided a memorable moment in a game that extended the Spurs’ winning streak to seven games. The dunk came with 1:54 remaining in the third quarter. Wembanyama found Castle cutting toward the basket and floated the ball toward the rim. Castle rose to meet the pass and threw it down with authority, finishing over Cardwell as the Spurs pushed their lead to 92-76.
