Is Phillies infielder Aidan Miller hurt? Bryce Harper reveals worrying update on top prospect

The Philadelphia Phillies have a roster capable of winning the World Series. While they didn't make many changes this offseason, with only Adolis Garcia and Brad Keller being new faces, the team is still in great shape.

But, if they could improve in one area, it would be at third base with Alec Bohm. Instead, the Phillies could turn to Aidan Miller as the replacement for Bohm. The Phillies top prospect has a lot of hype heading into the 2026 season.

However, as Destiny Lugardo of Phillies Nation shared on Twitter/x, during an interview, Bryce Harper revealed some concerning news. Miller is apparently not healthy.

Bryce Harper reveals worrying Aidan Miller injury news

"Miller... get off his butt and get in the game, that'd be nice," Harper said. "I need him to get healthy; he could help us by the end, obviously."

With Harper implying that Miller is hurt, the Phillies are now potentially down one of their top prospects for a period of time. Miller has yet to make an MLB debut or play in a game so far this Spring.

Now, after Harper's update, the reason seems to be clear: Miller isn't healthy enough to play. The 21-year-old top prospect of the Phillies has garnered a lot of hype in the last year.

Following a breakout 2025 campaign, where he hit 14 home runs, had an .825 OPS, and finished with a remarkable 59 stolen bases, Miller looks to be a future superstar.

He could take over for Bohm at third base this season, but based on this update from Harper, that doesn't look like a possibility any time soon.

Harper didn't reveal a timeline for Miller, what the injury is, or even anything beyond simply that he is hoping for Miller to get healthy.

But these comments from Harper are still very concerning for the Phillies. Hopefully, more is revealed on Miller's injury in the coming days, and the Phillies' top prospect's status can be determined to either deliver bad news or give Phillies fans a sigh of relief.
