The Phillies promoted Miller from Single-A Clearwater to High-A Jersey Shore on Monday, Jonathan Mayo of MLB.com reports.
Miller had been stuck in a 6-for-41 slump at the plate over his final 12 games at Clearwater, but he didn't compromise his plate discipline amid the dry spell, as he had still walked at a 20.4 percent clip. The 20-year-old was able to force his way to Jersey Shore after slashing .275/.401/.483 on the season at Clearwater while going 9-for-10 in stolen base attempts. He's regarded as one of the top lower-level prospects in the Phillies' system.

Phillies' Aidan Miller: Best hitter in Florida State League
Rotowire
Miller is slashing .337/.420/.570 with four home runs, nine steals and a 19 percent strikeout rate in 100 plate appearances for Single-A Clearwater.
Seen as one of the top prep hitters in last year's draft, Miller played only 10 games at Single-A last year, and he has dominated in a return to the Florida State League. Only Nick Morabito, who is over a year older than Miller and has since been promoted to High-A, has a higher wRC+ among qualified FSL hitters, so Miller should be getting his own promotion to High-A in the coming weeks. While most evaluators expect Miller to end up at third base, he has played only shortstop and designated hitter thus far in pro ball.
