After five seasons as manager for the Boston Red Sox, John Farrell is out of a job.
Farrell had one year remaining on his contract after the Red Sox picked up his 2018 option last December. It also did it despite starting the season with $217 million pitcher David Price on the disabled list and watching as 2016 Cy Young Award victor Rick Porcello stumbled to an 11-17 record.
"The Red Sox announced today [Wednesday] that John Farrell will not return as manager in 2018".
During his time with Boston, Farrell led the team to a 432-378 record with three division titles (2013, 2016, 2017) and a World Series title in 2013. We asked ESPN.com's David Schoenfield and Red Sox reporter Scott Lauber to weigh in on who might be the next manager.
