The Red Sox acquired left-handed reliever Matt Thornton from the White Sox in exchange for Minor League outfielder Brandon Jacobs on Friday night. To make room for Thornton on the 40-man roster, the Red Sox transferred Miller to the 60-day disabled list. The Boston Red Sox, acting swiftly after losing Andrew Miller to a season-ending foot injury, announced Friday night that they have acquired left-handed reliever Matt Thornton and cash for minor-league outfielder Brandon Jacobs. He has made 40 appearances this season for the White Sox and has held left-handed hitters to a .173 average , though three of the four home runs he has given up have been to left-handed hitters. The 23-year-old, who was ranked the organization's No. 11 prospect, combined to hit .246 in 83 games between the two clubs, with 24 doubles, one triple, 11 home runs, 44 RBIs, 33 walks and 90 strikeouts.
