Rockies prospect Braylen Wimmer, a 2023 eighth-round pick who reached AA Hartford this past season, was recently diagnosed with a brain tumor, for which surgery was required.
Wimmer was one of the Rockies’ minor-league players sent to the Arizona Fall League to play with the Salt River Rafters. He was nearing the end of the season when, according to a family friend, he suffered a seizure en route to a game, leading to the Nov. 1 diagnosis.
Wednesday, Wimmer’s alma mater, South Carolina, and the Rockies’ high-A affiliate, the Spokane Indians, posted messages of support for Wimmer:
