Dallas split 2023 between Clearwater and Jersey Shore, and began his pro career with Clearwater in 2022. The Phillies signed Dallas as an undrafted free agent in 2022 out of Lamar University.

Harper, 26, began the season with Reading, but was limited to just six outings as he was on the injured list from Apr. 8 to June 17.

Harper split 2024 between Jersey Shore and Reading, posting a 2.82 ERA (16 ER, 51.0 IP) over 44 total appearances. Harper spent all of 2023 and '22 with Clearwater to begin his pro career. The Phillies drafted Harper in the 17th round in 2022 out of Kentucky.

McCollum, 26, has proven to be a reliable piece out of the Fightin Phils bullpen in 2025. For the second-straight season, McCollum is poised to lead the Fightin Phils in saves, as he currently has nine. He began the season with Jersey Shore, posting a 1.13 ERA (1 ER, 8.0 IP) over seven games prior to being promoted to Reading on May 1. McCollum spent all of 2024 with the FIghtin Phils and split '23 between Reading and Jersey Shore. He pitched for Clearwater in all of 2022 and '21.

McCauley spent his second season with the Fightin Phils in 2025, working as a Pitching Coach, along with Brad Bergesen. He served as one of the team's pitching coaches in 2024, along with Phil Cundari. McCauley spent 2023 as the pitching coach under former R-Phils Manager Shawn Williams with the FCL-Phillies. It was his first full season with the Phillies as he was hired in July of 2022 by the organization. Prior to joining the Phillies, McCauley spent one year as an Assistant Coach at Troy University in Alabama. Before joining Troy, McCauley worked as a Pitching Coach and Strength/Conditioning Coach for Cressey Sports Performance. McCauley pitched collegiately for Michigan State from 2016-18, where he posted a sub 2.50 ERA in his first two seasons as a reliever.
