Rafael Castro

Rafael Castro is a two-way rookie center whose stocks-and-rebounding college profile makes him Milwaukee's most actionable waiver contingency if Myles Turner is traded.

Team: Milwaukee Bucks · Position: C · Contract: two-way · Age entering season: 23

Fantasy case

Castro averaged 15.3 points, 9.1 rebounds, 1.8 steals, and 1.7 blocks in 27.3 minutes across 27 games as a George Washington senior, shooting .627 from the field and .661 from the line. He transferred from Providence and took All-Atlantic 10 second team and A-10 All-Defensive honors in each of his two seasons there, finishing as the program's career field-goal percentage leader at .644. He went undrafted in 2026 and agreed to a two-way contract with Milwaukee on June 24, worth roughly $679K if held all season.

The scouting shape is narrow but real: 6-10, long, a two-season record of combined steal and block rates that few college bigs reach, and finishing efficiency that comes entirely from the rim. He attempted no three-pointers as a senior, which is the limitation that kept him out of the draft and caps his NBA role at backup five.

Low/base: Wisconsin Herd work and inactive-list nights. High: Turner is traded — Toronto, Atlanta and Charlotte have all been linked — and the backup-center minutes behind Kel'el Ware come down to Castro and Jericho Sims. In that branch he is a rebounds-and-blocks streamer in deep formats, not a standing roster piece.

Learning notes

Two-way bigs are worth tracking only when the team above them is thin and unstable. Milwaukee qualifies: one starting-caliber center under 25, one veteran center on the trade market, and a 45% youth-forward scenario. Castro's actionable signal is a Turner trade, not a Summer League line.

Career record

Pre-NBA: Five college years. Providence: 2021-22 redshirt, then sparse reserve minutes (1.8 PPG in 2022-23, 2.9 PPG across 34 games in 2023-24). George Washington: 2024-25 breakout at 14.0 PPG/8.9 RPG, then a 2025-26 senior year of 15.3 PPG, 9.1 RPG, 1.8 STL and 1.7 BLK in 27.3 minutes on .627 FG/.661 FT — second-team All-Atlantic 10 and A-10 All-Defensive both GW seasons, NABC All-District first team, Lefty Driesell national defensive player of the year finalist. Draft: undrafted (2026); signed a Milwaukee two-way June 24, 2026.

No NBA record. Most recent season: 2025-26 at George Washington (above); his professional file opens with the Wisconsin Herd in 2026-27.

Durability: No injury flags in the college record; the thin Providence usage was role-based, not health-based.

Trajectory: The record shows a late-blooming rim-running big whose two GW seasons produced a steal-plus-block combination few college centers match, with all of his efficiency at the rim and zero three-point attempts as a senior — which is why he went undrafted. He competes for third-center standing behind Ware and Sims in 2026-27, with the Herd as his default address. He becomes fantasy-relevant only in the Turner-trade branch where Milwaukee's center depth collapses to Ware plus him and Sims; in that world he is a deep-league rebounds-and-blocks streamer during call-up stretches, nothing more.
