The Phillies fired hitting coach Joe Dillon and infield coach Juan Castro Sunday afternoon. Assistant hitting coach Pedro Guerrero wasn’t let go but was given permission to look for other jobs, as the Phils intend to let their next hitting coach hire his own assistant. The rest of Philadelphia’s coaching staff will return in 2021, according to manager Joe Girardi.
“I think they [Dillon and Castro] worked extremely hard, but we just felt at this time it was time to make some changes,” Girardi told The Philadelphia Inquirer’s Scott Lauber and other reporters. “We always talk about, at this level, it’s a production-based business. It’s difficult.”
Dillon was in his second season as hitting coach, and across the board, the Phillies’ offensive numbers declined. After hitting a collective .257/.342/.439 (108 wRC+) in 2020, Philadelphia batters took a .240/.318/.408 slash line (93 wRC+) into Sunday’s season finale. Even with Bryce Harper enjoying an all-world season, the Phillies weren’t much beyond middle-of-the-pack in most major offensive categories.
