The Red Sox have acquired All-Star closer Joel Hanrahan from the Pittsburgh Pirates in a six-player deal.

Boston completed the trade Wednesday, also receiving infielder Brock Holt. The Red Sox gave up right-handers Mark Melancon and Stolmy Pimentel, infielder Ivan DeJesus Jr. and first baseman-outfielder Jerry Sands. Over the past two seasons, the righthanded Hanrahan had 76 saves, fourth most in the National League.
