Two games into the NBA Finals, Stephon Castle and the San Antonio Spurs looked finished. Down 0-2 to the New York Knicks and walking into a Madison Square Garden that wanted to bury them, the 22-year-old guard instead delivered the performance that flipped the series. San Antonio's Game 3 win cut the Knicks' lead to 2-1, and the loudest verdict on who made it happen came from ESPN's Mike Greenberg.
"If you were just parachuted in from another planet and didn't know any of the people, you'd have said, 'That guy, Stephon Castle, is the best player in this game,'" Greenberg said on Get Up. "I would have said Stephon Castle is the reason San Antonio won."
That is heavy praise on a night Victor Wembanyama scored 32 points on 11-of-18 shooting with six assists and a single turnover. But Castle was the one closing the door. He poured in 18 points in the first half, hit a contested three in the final two minutes, then walked to the free-throw line with about seven seconds left and the entire arena howling at him.
"I shoot pressure free throws every day," Castle told TNT's Inside the NBA crew afterward. "Obviously you can't simulate anything like this, but I step to the line in those moments. It's me and the rim."
He made both. Asked separately by ESPN's Malika Andrews what was going through his mind with the Garden booing him, Castle shrugged it off. "I don't want to say I didn't hear them, but I think I was just so locked into the game that I don't think it really mattered," he said. "Just stay poised. Take a deep breath. It's the same shot we shoot every day, so just go knock it down."
The other half of his night was on Jalen Brunson. Castle, who also drew the assignment on Shai Gilgeous-Alexander in the conference finals, spent 48 minutes hounding the Knicks' captain. "Just trying to tire him out throughout the game, keep my aggressiveness on him," he said. "The way they use angles, deception, pump fakes — I'm just really trying to stay disciplined and make everything tough."
The bigger story for San Antonio was composure. The Get Up panel framed Game 3 as a study in poise: the veteran team in its own building lost it, while the young team facing elimination at 0-2 held it together and made the plays that mattered. Castle, who with Wembanyama became the first pair of teammates to each post 20 points, five rebounds and five assists in a Finals game at age 22 or younger, said the maturity showed in what the Spurs didn't do after the buzzer.
"None of us really celebrated or got too excited. We kind of just walked back to the locker room," Castle said. "We all just want to win. We don't care who really puts the ball in the basket. I'm not going to get satisfied with just one win, knowing we came here to get two."
Wembanyama had already called Castle the most mature player on the roster — a label Castle waved away. "I think we have a very childish team as a whole, so maybe I'm just the least childish," he said. "But I wouldn't say I was the most mature."
He was loose enough to credit a pregame ritual that has nothing to do with film study. "I eat some green grapes, red grapes right before I go shoot," Castle said of a superstition he picked up late last season. "I don't know if that's what made me play well, but it's been working, so I'm not going to go away from it."
Whatever the recipe, San Antonio walked out of Game 3 believing it can steal the series. "I expect us to win the next three," Castle said, "but we're taking it game by game." Game 4 is back at the Garden, where the Knicks now have to prove Game 3 was the anomaly — and that the young guard who beat them on their own floor won't do it again.
