The Boston Red Sox added an arm to their bullpen on Friday night, acquiring left-hander Matt Thornton and cash from the Chicago White Sox for minor-league outfielder Brandon Jacobs.
To make room for Thornton on their 40-man roster, the Red Sox transferred injured left-hander Andrew Miller (left foot) from the 15-day to the 60-day disabled list. Miller was hurt Saturday in a game against the Angels and will undergo season-ending surgery, creating a need for a left-handed reliever.
Thornton, in his 10th major-league season, is 32-41 with a 3.53 ERA in 586 appearances, including one start. This year, he is 0-3 with a 3.86 ERA in 40 appearances.
Jacobs, a 10th-round draft pick in 2009, hit 11 homers and drove in 44 runs for Class A Salem before a recent promotion to Portland.
The White Sox's cash payment in the deal was $750,000, according to WEEI.com. Thornton, 36, is owed the balance of his $3.5 million salary this season and a $1 million buyout of his $6 million option.
