Where are each of the Phillies' top prospects starting the season?

Phillies Top 30 prospects starting the season in Low-A

The Clearwater Threshers are the Phillies' Low-A affiliate and host the Phillies spring training squad at BayCare Ballpark each February and March. Low-A is much like High-A, but it usually is home to the younger prospects. However, it can also be the place to find hidden gems in the system.

Aidan Miller, 3B/SS, Phillies No. 3 prospect (MLB No. 56)

Aidan Miller has been the talk of the town for anyone associated with Phillies development over the past year.

With a strong showing in his first taste of professional ball last year, the Florida native has rocketed up many people's top prospect list, finally landing at the No. 3 spot behind two pretty good names in Painter and Abel.

The 6-foot-2 righty dropped significantly down the draft board in 2023 due to a broken hamate bone before his final season of high school. The Phillies were able to steal him at pick 27 in the first round, and Miller has shown nothing but promise since then.

Miller boasts a great hit tool for a 19-year-old, grading at a 60 while also being athletic around the diamond. While most projections have him sticking as a third baseman long-term, he has the athleticism and quickness to play an above-average shortstop at most levels.

The Phillies see a lot of potential in Miller. Assistant general manager and director of player development Preston Mattingly spoke highly about him on the High Hopes podcast with Jack Fritz and James Seltzer. With no long-term commitment to their current third baseman, Alec Bohm, it could just be a matter of time before we see a change at the position in just a couple of seasons.

If there is a reason to watch Single-A baseball in 2024, it's Miller. The pop in his bat, mixed with his ability in the field, points toward a bright future, hopefully in red pinstripes.

Other Notable Low-A prospects: Nikau Pouaka-Grego, Kehden Hettiger, Raylin Heredia, TJayy Walton, Alex McFarlane, Devin Saltiban, Orion Kerkering (Rehab assignment)

Phillies Top 30 prospects starting the season in Rookie Ball

The Rookie-level league is a shortened-season league that contains the youngest, freshest players in MLB organizations. Oftentimes, these teams include players who were recently signed or drafted from the amateur circuit. Players in these leagues split time with each other, working more on development and growth rather than in-game statistics and championships.

Starlyn Caba, SS, Phillies No. 5 prospect

Starlyn Caba, 18, played in only 31 professional games last season but quickly impressed. Seen as one of the top signings of the 2023 international signing class, the Dominican Republic native made a massive jump from the No. 23 prospect in 2023 all the way to the fifth spot to begin 2024.

The switch-hitter has the make-up to be successful, as his great defensive skills leave his overall floor as a player higher than most. Much like some of the other players noted before, Caba has a great hit skill with the ability to put the bat on the ball, striking out less than 10 percent of the time while walking over 17 percent.

Being an 18-year-old kid in a professional baseball organization might seem like a lot to handle for most, but Caba has been impressive up to this point. A calm, composed hitter with elite defensive ability from shortstop or second base, Caba is a strong candidate for promotion into Low-A to begin his journey seeing increased competition, growing into his body and finding his power stroke.

Other Notable Rookie Ball Prospects: Eduardo Tait, Alexis De La Cruz, Jalvin Arias
