After posting their first 90-loss season since 1966, the Boston Red Sox officially announced John Farrell as their new skipper to replace Bobby Valentine.

Farrell spent the last two years with the Toronto Blue Jays, and signed a three-contract with Boston through 2015. To compensate Toronto, the Red Sox sent shortstop Mike Aviles and also received right-hander David Carpenter.

Farrell was the Boston pitching coach from 2007 to 2010 before he took the helm as Toronto’s manager. He posted a 154-170 record in two seasons with the Blue Jays.

The Red Sox fired Valentine the day after the season ended. Boston finished with a 69-93 record, and let Valentine go after only one season.

Valentine clashed with the players and media. He was originally brought in to clean up a clubhouse that lacked discipline, with players reportedly drinking beer and eating fried chicken during games under then-manager Terry Francona in 2011.
