Following Brian Kaplan’s resignation, the Phillies name a new assistant pitching coach.
The Philadelphia Phillies have now formally announced that they have fired the head coach and reached a new deal to hire a new one.
Mark Lowy was elevated to assistant pitching coach by the Phillies on Wednesday.
The news was made the day after Brian Kaplan, the previous director of pitching development and assistant pitching coach, departed the team to take a position as pitching coach with the Arizona Diamondbacks.
The 32-year-old Lowy joined the Phillies in 2021. Prior to being employed full-time as a pitching development analyst in 2022, he began working part-time in the club’s player development division. Before moving to the major league team in 2024 as the main pitching development analyst, he served as an upper-level pitching coordinator in 2023.
Before joining the Phillies, Lowy, a graduate of Gettysburg College, collaborated with Kaplan at Cressey Sports Performance in Palm Beach Gardens, Florida.
Caleb Cotham, the Phillies’ pitching coach, will be back for a fifth season. Bullpen coach Cesar Ramos will return for a second season.
Kaplan, who co-founded Cressey Sports Performance, was the assistant pitching coach for the Phillies for three seasons. Sam Fuld, who is stepping down part of his GM responsibilities to attend the Wharton School of Business to earn an MBA and take over as the Phillies’ president of business operations in May 2026, was the one who initially brought Kaplan on board.
