Prospect Rankings
Role: Mid Rotation Starter/Late Inning Reliever
Risk: Extreme – Pan had one appearance in 2023 that could be classified as a start, but this is the role he will reportedly be in for the 2024 season. His fastball is his only really fully formed pitch, and while you can see the outline of his secondary pitches, they aren’t there yet.
Summary: Pan was the Phillies second biggest signing of the 2023 signing period behind Starlyn Caba. He was not the usual international signing, as he was already 20 with an international track record and experience in his native Taiwan. He does not have a projectable frame, but there is still some maturation and strength to be gained. The good news is that he does not really need to grow into more velocity. He would fade in his “starts” and deep into pitch counts, but Pan routinely averaged over 96 in his appearances and was up to 100. He releases from a fairly over the top, but still high, delivery so he doesn’t get ideal plane on his fastball, but he will get large (20”+) IVB when he is consistently on top of it, and he managed a 31% whiff rate on the fastball with Clearwater, while also throwing it in the zone a lot. His secondary pitches are a bit murkier. He arrived with a whole bevy of pitches, and he threw a bunch of different versions of things over the course of the year. Right now the Phillies are working on narrowing him down to a splitter and a slider to go with the fastball. He gets very low spin on his splitter (just 600 RPM on average) and it actually moves more glove side than his fastball, almost like a cutter. He struggled to command it, with hitters swinging and missing, but he also struggled to throw it for a strike. His slider sat in the low 80s and is more vertically oriented, and he got even more swings and misses on it than the splitter, but he struggled to throw it for strikes just as much. It was a bit of a weird year for Pan, as he signed with the org in January and had a bunch of habits and training from his time in Taiwan that made it difficult to just throw him out as a starter in 2023. He faded down the stretch and was used as a closer late in the year. There is a case he should just be a reliever, and he could move quickly in that role. His fastball will play in any role, and if he can harness both offspeed pitches, he could be an effective starting pitcher. The Phillies will also need to increase some of his strength and durability, so he can hold his stuff deeper into his starts.
2024 Outlook: Even with the potential move to the rotation in 2024, Pan likely goes to Jersey Shore to open the season. Despite signing last year, he is already 21 years old and the Phillies are unlikely to baby him along.
Pan is about the age of a college sophomore and looks to have a good fastball, a starter’s arsenal, and control issues. This puts him in a similar position to a Christian McGowan and Orion Kerkering group of prospects.
