Why Brian Bannister is leaving the Red Sox

By WEEI 93.7

Brian Bannister has long been viewed as a key bridge for a Red Sox organization trying to stay ahead of the curve with analytics and overall pitching information.

His presence and expertise were valued so much by the Sox that Bannister was brought onto the major league coaching staff as the assistant pitching coach, helping implement the kind of technology that is starting to change the way pitchers approach the game.

But now he has moved on, heading to the San Francisco Giants become their director of pitching.

I want to specifically thank Chaim Bloom and Brian O’Halloran - they are incredible leaders and the Red Sox will be in good hands for a very long time. Thank you to the coaches and support staff, it was a privilege winning a World Series with you in 2018 and all the best in 2020.

The move is motivated by the same reasoning that originally adjusted his role with the Red Sox after the 2019 season: Family.

As Bannister pointed out in a text following the announcement that he wouldn't be staying on the big league staff: "This year I spent 210 days in a hotel from February through the end of September while splitting time between the Major League team and the minor league development side." 

By working with the minor leaguers his schedule would have been 20 days on the road and then work from home for the other 10 each month.

But the arrangement with the Giants is an even better solution considering his family -- which includes sons who are 11 and 7 years old, respectively -- lives in the Bay Area.
