OAKLAND, Calif. — The Red Sox did not wait until closer to the trade deadline to improve their bullpen. On Friday night they obtained lefthander Matt Thornton from the White Sox in exchange for Double A outfielder Brandon Jacobs.
The White Sox, sources said, also included $750,000 in the deal to cover some of the $3.47 million Thornton has remaining on his contract. He is owed $2.47 million for this season. There is a team option for 2014 or a $1 million buyout.
The Sox needed relief help, specifically a lefthander, when Andrew Miller suffered a foot injury in a game against the Angels last Saturday and was lost for the season. That left Craig Breslow as the only lefthander in the bullpen. Full story for BostonGlobe.com subscribers.
