The Red Sox acquired Conor Jackson from the Athletics for Jason Rice, the teams announced. Oakland sent cash to Boston in the deal and the Red Sox transferred right-hander Bobby Jenks to the 60-day disabled list to create 40-man roster space for Jackson.
Jackson, 29, can fill in at the corner positions for the Red Sox and provide a right-handed bat off of the bench. He has a .249/.315/.342 line in 368 plate appearances this year and boasts a career line of .286/.384/.441 against left-handers. The 2003 first rounder was a key contributor for the D'Backs from 2006-08, but his offensive production has fallen off since. Jackson earns $3.2MM this season before hitting free agency.
Rice posted a 3.69 ERA with 9.4 K/9 and 4.4 BB/9 in 85 1/3 innings of relief for Boston's Triple-A affiliate this year. In 256 career minor league appearances, most of which have come out of the bullpen, the 25-year-old has a 3.91 ERA with 9.8 K/9 and 5.2 BB/9. The White Sox selected him in the 11th round of the 2005 draft. MLB.com's Jane Lee first reported the move.
