Don Mattingly leads the Phillies managerial market at 66.5% implied probability after guiding the club from a 9-19 start under Rob Thomson to a 79-55 finish and Wild Card berth in 2026. Recent reports indicate Alex Cora has declined the vacancy for a second time, preferring time away from managing in 2027, which removes the front office’s preferred external option and elevates Mattingly’s standing as the in-house candidate under contract through 2027. His clubhouse respect and familiarity with the roster provide a low-disruption path ahead of a potential lockout. Rocco Baldelli sits second at 17.5% as the leading alternative with prior managerial experience and recent Dodgers ties, while lower-priced names such as Brad Ausmus and Brandon Hyde reflect broader but less immediate interest in the search.
