What’s your concern level with Aidan Miller?

Imagine being told in the offseason that Alec Bohm would be hitting .180 with a .527 OPS through the Phillies first 41 games. One of your first thoughts after a slew of expletives would probably have been “well at least that’s giving Aidan Miller a golden opportunity”, and you wouldn’t have been wrong!

But that would have been before knowing about Aidan Miller’s back injury. The mysterious ailment, which the Phillies have declined to go into detail about, has prevented Miller from appearing in any games since the end of spring training. In fact, he has not even swung a bat yet and has not advanced to baseball activities as was reported on May 6th by TGP contributor Jeff Kerr.

Two days later, MLB.com’s Todd Zolecki mentioned on The Phillies Show podcast that Miller had suffered what Zolecki calls a “setback” after starting to field ground balls and ramp up baseball activities.

The shroud of mystery over the injury adds to the worry, but as Zolecki mentions in the video clip, this perhaps could be the Phillies exercising extreme caution with a top prospect. They obviously showed their willingness to do so with how they handled Andrew Painter’s elbow injury in 2023. Of course, these are two different injuries to two different players as elucidated by Phillies prospect expert Matt Winkelman.
