Stephon Castle Is Earning His Stripes as One of the NBA’s Premier Two-Way Guards
"I take a lot of pride in that... I ask for those matchups. I wouldn't want it any other way. I feel like I can be one of the best perimeter defenders in the league."

San Antonio Spurs guard Stephon Castle isn’t just embracing tough assignments-he’s asking for them. Night in and night out, the rookie-turned-breakout star is taking on some of the NBA’s most dangerous scorers, including All-Stars Luka Dončić and Shai Gilgeous-Alexander. And he’s not backing down.
Whenever the Spurs face the Lakers or Thunder, Castle is the one stepping up to the challenge. For a young guard in just his second season, that’s no small task.
But Castle isn’t just surviving-he’s making a name for himself on both ends of the floor. With a polished offensive game and a defensive motor that doesn’t quit, Castle is quickly becoming one of the most complete young guards in the league.
“I take a lot of pride in that. I ask for those matchups.
I wouldn't want it any other way,” Castle said on NBA Today. “I feel like I can be one of the best perimeter defenders in the league.
Day in and day out, I'm just trying to prove that.”
Harrison Barnes advocated that at least one of his two Spurs teammates should have been named an All-Star alternate for Steph Curry:

That mindset has already paid dividends for San Antonio. In December, the Spurs rattled off three straight wins over the Thunder in a 12-day span-including a Christmas Day blowout-and Castle’s defense played a major role.
Gilgeous-Alexander, one of the league’s most efficient scorers, was held to 22 points on 7-of-19 shooting, including just 1-of-6 from three. That’s no accident.
That’s Castle putting in the work, studying tendencies, and making life difficult for one of the best in the game.
And it’s not just the defense that’s turning heads. Castle is stuffing the stat sheet, too.
In a 138-125 win over the Dallas Mavericks, he made NBA history by becoming the youngest player ever to record a 40-point triple-double with at least 12 assists and 12 rebounds. He also added three steals and a block for good measure.
That kind of all-around performance isn’t just rare-it’s historic.
With Warriors star Stephen Curry sidelined due to a knee injury ahead of All-Star Weekend, the conversation turned to who might deserve a spot in his place. Spurs veteran Harrison Barnes didn’t hesitate to throw Castle’s name into the mix-and he made a strong case.
“It would be criminal if him and Fox didn’t get a look. We’re No. 2 in the West,” Barnes said. “I think for what we’ve done, for the teams that are below us that had two All-Stars, I don’t know a case-if we’re talking about impact on winning and playing high-level basketball-why either of them shouldn’t be selected and/or highly under consideration for those spots.”
Ultimately, the NBA selected Toronto’s Brandon Ingram to replace Curry, while Castle’s backcourt partner, De’Aaron Fox, was named as the injury replacement for Giannis Antetokounmpo.
Still, Castle’s breakout season has made one thing clear: he’s not just a promising young guard-he’s already impacting winning at the highest level. Whether it’s locking down elite scorers or making history with a triple-double, Castle is proving he belongs in the conversation among the league’s best two-way players. And if this is just the beginning, the Spurs might have something special on their hands.
