Don Mattingly leads the market at 22% after Alex Cora twice declined the Phillies' overtures, citing family priorities, shifting the search inward following Rob Thomson's mid-April dismissal. Mattingly guided the club from a 9-19 start to a 79-55 finish and NL Wild Card berth, earning strong clubhouse support despite the postseason exit. Brad Ausmus benefits from his longstanding ties to president Dave Dombrowski dating to their Tigers tenure, while Rocco Baldelli brings proven AL Central success and recent front-office experience with the Dodgers. The wide field reflects a deliberate process ahead of a potential lockout, with external candidates like Will Venable and Brandon Hyde offering varied experience levels against Mattingly's established rapport and contract security through 2027.
