Stephon Castle lowered the boom (and then some) during Wednesday’s Game 2.
The San Antonio Spurs guard Castle produced the dunk of the NBA playoffs on Wednesday against the Oklahoma City Thunder. In the second quarter at Paycom Center in Oklahoma City, Okla., Castle charged into the paint off a kick-out by his Spurs teammate Victor Wembanyama … and proceeded to commit an aggravated assault on a rotating Isaiah Hartenstein.
The seven-footer Hartenstein proved to be little more than a court decoration to Castle, who cocked the ball back with one hand and then threw down a violent dunk over Hartenstein’s head. Here is the crazy video.

Castle is already a tall guard at 6-foot-6, and he plays even bigger than that with his cartoon-like bounce. The 2025 NBA Rookie of the Year Castle participated in the Slam Dunk Contest last year and has also wreaked other kinds of havoc with his rim-wrecking ability in the past. But Castle produced his very best work yet with that cruel attempt on the life on Hartenstein in Game 2.
