​Normally, there would be no minor league update for today, since the full season affiliates did not play yesterday.However, this is a special, complex-league-only update because Sebastian Walcott, the top prospect in the Rangers’ system and a consensus top 25 prospect in MLB, made his 2026 debut yesterday. Walcott has missed all of 2026 after undergoing internal brace surgery back in February, and began a rehab assignment with the ACL Rangers on Tuesday.AdvertisementAdvertisementAdvertisementWalcott was the DH and went 1 for 3 with a strikeout and a double before being lifted after three plate appearances. He will presumably continue to play in Surprise at least through this week before joining either Frisco or Round Rock.2024 3rd rounder Casey Cook, who also has been sidelined this season, is on game five of his rehab assignment in Surprise. Cook was 2 for 4 with a triple, and is slashing .400/.500/.800 in 18 plate appearances for the ACL Rangers. Cook had a disappointing 2025 season, slashing .205/.302/.294 for Hub City, and my guess is that he will return to Hub City once he’s ready to go.Two-way guy Seong-Jun Kim threw two shutout innings, walking two and striking out three.2025 20th rounder Jay McQueen was 2 for 4 with a homer. 2025 17th rounder Noah Franklin was 2 for 4. Jack Wheeler homered.ACL Rangers box scoreDSL Rangers Red box scoreDSL Rangers Blue box score
