MLB News: Former Dodgers Manager Makes Baseball History With New Role

He also owns the highest winning percentage for a manager in Phillies franchise history, as detailed by Matt Gelb of The Athletic.

This season, however, the Phillies started 9-19, including losing 11 of their past 12 games.

That rough start comes after the Phillies were the preseason favorites to again win the division and boast one of the five most expensive rosters in the sport, which is also the largest payroll in the history of the franchise.

As for the team’s hopes for the rest of 2026, it’s unclear if Mattingly can fully right the ship, Gelb said.

“The Phillies have not hit, their reliable rotation has failed them, and the defense has been erratic at best,” he wrote. “Absent a major roster shakeup, the Phillies are banking on a managerial change sparking something.”

What was Don Mattingly like as the Dodgers’ manager?

Mattingly’s five years at the helm in Los Angeles showed marked improvement, though he never won the pennant.

From his first season of 2011, in which the Dodgers had a 82-79 record but finished third in the NL West, Mattingly and the Dodgers only improved.

In 2012, the Dodgers went 86-76 and finished second in the division but missed the playoffs.

In his final three seasons, the Dodgers won the NL West each time and qualified for the postseason, with the best result coming in a NL Championship Series loss to the St. Louis Cardinals in 2013.

Those three straight division titles were the first time in Dodgers history the feat had been accomplished, per ESPN.

Mattingly stepped down as Dodgers manager in 2015 and was hired a week later by the Miami Marlins.
