Baseball America celebrates the top performances by prospects at every position by naming a Minor League All-Star team at the conclusion of each season.
This year’s team was selected by BA staff. Players are listed at the highest level they achieved this season.
C Adrian Del Castillo, Diamondbacks
Triple-A Reno
Del Castillo scuffled at Miami in his draft year of 2021 and for two seasons in the D-backs’ system. That tide began to turn this season, when everything clicked for the 24-year-old lefthanded hitter in the Pacific Coast League. Del Castillo led the minor leagues with a .603 slugging percentage and 1.002 OPS and also finished fourth with 65 extra-base hits despite spending more than a month in the big leagues, where he filled in for an injured Gabriel Moreno.
1B Bryce Eldridge, Giants
Triple-A Sacramento
On the surface, Eldridge had a good year. In context, he had a great one. Drafted 16th overall out of high school in 2023, Eldridge played at all four full-season levels of the Giants’ system this year as a 19-year-old. He hit 23 home runs, which may not be an elite total for a first baseman but tied for the lead among teenagers this season. Not many under-20 players top 20 homers in a minor league season, but some recent age-19 prospects to do so include Francisco Alvarez, Junior Caminero and Jackson Chourio.
2B Kristian Campbell, Red Sox
Triple-A Worcester
Campbell charted one of the more meteoric prospect rises of recent vintage. From fourth-round pick out of Georgia Tech in 2023 to breakout prospect of the year a season later, he dominated three minor league levels this season by hitting .330/.439/.558 with 20 home runs and 24 stolen bases. Campbell’s on–base percentage and .997 OPS ranked second in the minors, and he and Andres Chaparro were the only two minor league hitters to bat 400 times and clear the .300/.400/.500 slash line thresholds. Add in versatility—he also plays shortstop and center field—and Campbell is one of the more well-rounded prospects in the game.
3B Coby Mayo, Orioles
Triple-A Norfolk
The Orioles’ run of impact rookies—from Adley Rutschman in 2022 to Gunnar Henderson in 2023 to Colton Cowser this year—will likely continue with Mayo in 2025. The 22-year-old made his MLB debut this season, and while he scuffled with irregular playing time, he…
