Wen-Hui Pan, RHP
Signed by the Phillies out of Taiwan at the beginning of the 2023 international signing period, right-handed pitcher Wen-Hui Pan has impressed in his limited professional career thus far. MLB Pipeline ranks him No. 20 in the Phillies top prospects, while Baseball America ranks him No. 16 in its most recent update. He was ranked No. 13 by Pipeline earlier this season, but a broken pinky finger delayed his start and dropped him down the rankings.
Pan, 21, debuted last season with the Single-A Clearwater Threshers and dominated in his 57 2/3 innings. He posted a 2.81 ERA and 36.2 percent strikeout rate in the Florida State League.
He got back into game action in late June this year with a rehab assignment that took him through the Florida Complex League (just for one inning) and Single-A again. In his 7 1/3 innings with the Threshers this season, Pan pitched to a 3.68 ERA with a 38.7 percent strikeout rate before getting the call to Double-A.

Since arriving in Jersey Shore on July 20, Pan has had even better results with the BlueClaws. In 11 appearances, he has a 1.50 ERA and 1.00 WHIP while striking out 27.4 percent of the batters he has faced.
According to his MLB Pipeline scouting report, the Phillies were looking at stretching Pan out with an eye to a starting role, but so far, he hasn't thrown more than two innings at a time this season. Both Pipeline and Baseball America think that he'll be ditching his changeup and curveball moving forward and working on his slider to pair with his 65- to 70-grade high-90s fastball and nasty 60-grade splitter. The Phillies feel his splitter is the best change of pace offering in the system (subscription required), according to Baseball America.
