WATCH: Aidan Miller crushed a first swing NUKE during batting practice that landed on the roof of Frenchy’s in left field

Dave Dombrowski didn’t have to say a word. He just stood there in Clearwater and watched Aidan Miller launch a batting practice ball clean over left field and onto the roof of Frenchy’s at BayCare Ballpark.

That’s not a cheap shot to the berm. That’s deep left. That’s grown-man juice. When your top prospect is hitting balls onto local seafood establishments with the president of baseball operations watching, that’s not just BP. That’s a message.

Aidan Miller is the crown jewel of the system. Baseball America has him as the Phillies’ No. 1 prospect. MLB.com ranks him No. 32 overall in the sport. He’s 21 years old and already forcing uncomfortable conversations in an infield that, on paper, is “set.”

He tore through Double-A Reading, finished 2025 in Triple-A Lehigh Valley, and showed a level of strike-zone discipline that most big leaguers never develop. He led the Eastern League in walks and stolen bases and was named a postseason All-Star.

The full-season line jumps off the page. Between Double-A and Triple-A, Miller hit .264 with 14 home runs, 42 RBIs, and 59 stolen bases. Fifty-nine.

He impacts the game in multiple ways, and when he found his rhythm late in the year, he looked like a different animal. Over his final 39 games, he slashed .356 with a 1.088 OPS. That’s a heater to close the year against upper-level pitching.

The Phillies already have Trea Turner, Bryson Stott, and Alec Bohm in the infield mix. On paper, there’s no obvious vacancy. In reality, Aidan Miller’s offensive ceiling is making that paper flimsy.

Dombrowski acknowledged he can play shortstop but noted they need to make sure he’s properly prepared if he’s going to move to another position. I look at this as the Phillies attempting to figure out how to make this work sooner than later, but we’ll see.

If the Phillies move on from Bohm, whether that’s at the deadline or after the season, Aidan Miller sliding into third base feels like the cleanest path. He’s athletic enough to handle it, he has emerging power, and he brings a different kind of edge to the infield.

When a 21-year-old is putting balls on rooftops in front of the front office and backing it up with elite plate discipline and 59 steals, he becomes a timeline. A strong Spring Training will have everyone questioning whether or not the Phillies can afford to wait on Aidan Miller any longer than they already have.
