Roots & the rise

A big, playmaking combo guard and Rookie of the Year — a rising two-way piece of the Spurs' young core.

Stephon Javonte Castle was born in Covington, Georgia and won the 2024 NCAA title as a freshman at UConn, earning Big East Freshman of the Year. San Antonio drafted him 4th in 2024, and he won 2025 Rookie of the Year plus Rising Stars MVP.

In 2025-26 he broke out — 16.7 points and 7.4 assists a game — headlined by a 40-point triple-double against Dallas, only the second in Spurs franchise history after David Robinson. A 6-foot-6 guard who scores and creates, he's a foundational piece alongside Wembanyama and Fox on a Finals team.

BEYOND THE GAME

Beyond the game

Basketball and San Antonio run in Castle's blood: his father, Stacey, was a teammate of Hall of Famer Tim Duncan at Wake Forest, a fitting thread for a player who became a Spur. Raised in Covington, Georgia by parents Quannette and Stacey, he was a McDonald's All-American before winning it all as a UConn freshman.

His identity is size and playmaking — a big guard who can run an offense, get downhill, and defend multiple positions. The 40-point triple-double that put him in franchise company with David Robinson signaled a leap from Rookie of the Year to genuine building block on a Spurs team with title aspirations.

ANALYSIS

What the numbers say

Size and playmaking

Castle's value is a rare combination for a young guard: 6-foot-6 with the vision to run an offense (7.4 assists) and the frame to defend multiple positions. His 40-point triple-double — franchise company with David Robinson — showed a scoring ceiling to match the playmaking, and at 21 he's a genuine two-way building block.
