Boston will immediately begin the search for a replacement.
Farrell had been with the team since the 2013 season. During his tenure, the Red Sox won three American League East titles (2013, 2016, and 2017) and a World Series championship in 2013.
Red Sox under Farrell
The 55-year-old’s future with the Red Sox appeared to be in doubt Tuesday when a report indicated president of baseball operations Dave Dombrowski would discuss Farrell’s fate with the team’s ownership group. That came a day after the Red Sox were eliminated from the American League Division Series in four games by the Houston Astros. In 2016, Boston was also eliminated from the ALDS in a sweep by the Cleveland Indians.
Farrell finishes with a combined 432-378 managerial record in Boston.
