Stephon Castle Broke Luka Doncic's NBA Playoff Record. The Spurs Are Back In The West Finals.

Stephon Castle posted 32 points, 11 rebounds, six assists, and five made three-pointers Friday night at Target Center as the San Antonio Spurs closed out the Minnesota Timberwolves 139-109 in Game 6 of their Western Conference semifinal. The 21-year-old shot 11-of-16 from the field and made his first five three-point attempts on his way to becoming the youngest player in NBA playoff history to record at least 30 points, 10 rebounds, five assists, and five made threes in the same game. The previous holder of that record was Luka Doncic. The Spurs are headed to their first Western Conference Finals since 2017, and the closeout was led by a former fourth overall pick whose own franchise has spent the spring putting Victor Wembanyama's name in every headline before his.

Castle entered the NBA as the No. 4 overall pick in the 2024 NBA Draft, taken behind Zaccharie Risacher, Alex Sarr, and Reed Sheppard. He came out of UConn, where he played one season under Dan Hurley and won the 2024 NCAA national title averaging 11.1 points, 4.7 rebounds, and 2.9 assists across 34 games. His college shooting splits were not the selling point; the Spurs front office bet on the frame, the on-ball defense, and the touch. The payoff was immediate. Castle won the 2024-25 Kia Rookie of the Year award averaging 14.7 points per game and leading all rookies in scoring and steals. He is the fourth Spur to win that trophy, joining David Robinson in 1990, Tim Duncan in 1998, and Victor Wembanyama in 2024. Three of those four players are still on the roster.

The series itself was less competitive than the 4-2 line suggests. San Antonio outscored Minnesota by 97 total points over six games and never trailed by more than ten in any single contest. Wembanyama, named regular-season Defensive Player of the Year by unanimous vote earlier this month, finished Game 6 with 19 points in 27 minutes — a workload reduction that says everything about the closing margin. De'Aaron Fox, the trade-deadline acquisition from the Sacramento Kings, added 21 points and nine assists. The Spurs scored 139 points without their best player needing more than half the floor time, and Castle's perfect five-for-five three-point line in the first half pushed what had been a one-possession game into a fourteen-point halftime lead. Anthony Edwards played the entire series on a hyperextended right knee suffered in round one; Donte DiVincenzo was already done for the postseason with a ruptured Achilles.

Mitch Johnson is the head coach. He was promoted on May 2, 2025 after Gregg Popovich stepped down following 29 seasons and a November 2024 stroke; Popovich now serves as team president of basketball operations. Johnson, who ran the bench as acting head coach for most of 2024-25, finished the regular season at 62-20 — the Spurs' first sixty-win year since 2016-17. Round one was a 4-1 series win over the Portland Trail Blazers. The franchise has not appeared in a Western Conference Finals since Kawhi Leonard's 2017 squad got swept by the Golden State Warriors in four games. Castle's Friday-night line pulled a record off Luka Doncic, the most-watched offensive player of the last decade.

Game 1 against the Oklahoma City Thunder tips Monday night at Paycom Center. The Thunder are the defending champions, swept their first two series of these playoffs, and have been off for over a week. Shai Gilgeous-Alexander, the reigning Most Valuable Player, is the matchup pressure point — Castle and Fox will trade the primary assignment, and the Spurs are likely to ask Castle to take the larger share of those minutes after his closeout work on Anthony Edwards. Chet Holmgren against Wembanyama is the other axis. Oklahoma City opened in Las Vegas as a 4.5-point home favorite for Game 1. Mitch Johnson has not coached a Western Conference Finals minute. Castle has not played one. Wembanyama and De'Aaron Fox have not either. The franchise itself has not since the second Obama term.

The 2024 NBA Draft class is producing in May. Castle is the headliner. Alex Sarr, the No. 2 pick to the Washington Wizards, watched Washington win the May 12 draft lottery from the front row — meaning his own team will likely add AJ Dybantsa, Cameron Boozer, or Darryn Peterson over the top of his depth chart in June. Reed Sheppard, picked one slot ahead of Castle at No. 3, has been on a thinning playoff rotation for the Houston Rockets. Castle is the only top-four pick from his class whose franchise stock is rising rather than getting diluted. The Spurs hold his rookie-scale four-year, $41.35 million deal through 2027-28 after exercising both team options last October. He is 21.
