Phillies Promote Top Prospects Including Aidan Miller to Triple-A

The Philadelphia Phillies have promoted their top shortstop prospect, Aidan Miller, from Double-A Reading to Triple-A Lehigh Valley as the 2025 season nears its end. Miller, a 21-year-old 2023 first-round draft pick, has rebounded strongly in the second half of the season, posting a .259/.382/.427 slash line with 13 home runs, 52 stolen bases, and an .809 OPS, earning Eastern League Player of the Week honors in August. His promotion comes amid uncertainty about the health of the Phillies' starting shortstop, Trea Turner, who suffered a hamstring strain, though Edmundo Sosa is currently the leading candidate to fill in if Turner is sidelined. Miller is ranked as the Phillies' No. 2 prospect and No. 47 overall by MLB Pipeline and is expected to continue developing at Triple-A, with a potential major league debut looking more likely in 2026. Alongside Miller, the Phillies also promoted infielder Aroon Escobar to Double-A Reading and outfielder Dante Nori to Reading, highlighting a strong farm system. Miller's advancement is viewed as a key step toward the Phillies' future roster plans as they pursue another postseason run.
