The Philadelphia Phillies announced they fired manager Rob Thomson on Tuesday after a rough start to the season.

The Phillies are off to a 9-19 start to the season, tied with the New York Mets for the worst record in baseball so far.

The team announced that bench coach Don Mattingly will become the interim manager. The team is promoting third base coach Dusty Wathan to bench coach, and promoting Triple-A Lehigh Valley manager Anthony Contreras to the big league staff, where he will assume third-base coaching duties.

The Phillies hired Thomson as the team’s bench coach prior to the 2018 season. He was named as the team’s interim manager on June 3, 2022, after the Phillies fired Joe Girardi.

After Thomson took over in 2022, the team went 65-46 and went all the way to the World Series before losing to the Houston Astros. He was named the full-time manager during the Phillies’ pennant run.

He guided the Phillies to the playoffs in each of the last three seasons as well, winning the National League East twice. Across five seasons, Thomson went 355-270 with the Phillies.

Despite the strong record from his prior three and a half seasons on the job, it wasn’t enough to save Thomson following the team’s dreadful start.

The Phillies are the second team to fire their manager, as the Boston Red Sox fired Alex Cora on Saturday.
