The Red Sox officially announced their deal with new manager John Farrell.
Farrell received a three-year contract. As compensation to the Blue Jays, to whom Farrell was under contract through 2013, the Red Sox sent shortstop Mike Aviles and received righthander David Carpenter.
The Red Sox said that they received permission to speak with Farrell and came to an agreement with him on Saturday night. Farrell was the Red Sox pitching coach from 2007-10 before becoming manager of the Jays for two seasons. He is the seventh manager in major league history acquired by one club while under contract to another.
"I'm extremely excited to be returning to the Red Sox and to Boston," Farrell said. "I love this organization. It's a great franchise in a special city and region, with great fans, and we want nothing more than to reward their faith in us."
"We are thrilled to name John Farrell as our new manager," general manager Ben Cheringto said. "John has been a major league pitcher, front office executive, coach, and manager. His broad set of experiences, and exceptional leadership skills, make him the ideal person to lead our team. I have known him in various capacities throughout my career, and I hold him in the highest regard as a baseball man and as a person."
"We met some outstanding managerial candidates in this process," said Red Sox President/CEO Larry Lucchino. "John Farrell brings a unique blend of managerial experience, leadership and presence, pitching expertise, front office experience, and an established track record with many members of our uniformed staff and members of our front office. He will hit the ground running."
Carpenter, 27, has struck out 60 in 60 innings over 67 career major league games, all in relief, with the Astros (2011-12) and Blue Jays (2012). He is 1-5 with one save and a 5.70 ERA in his big league career.
He appeared in 33 major league games in 2012, including 30 with the Astros prior to being sent to the Blue Jays in a 10-player trade July 20. He also pitched in 23 Triple A games for Oklahoma City and Las Vegas, going 1-1 with four saves, a 3.08 ERA, 25 strikeouts and only seven walks in 26.1 innings.
Originally a catcher, Carpenter converted to pitching midway through the 2008 season. Since that time, he has averaged 9.56 strikeouts per nine innings pitched in 178 career minor league games, all in relief.
