RS3The Boston Red Sox have lost their All-Star closer, Craig Kimbrel, to knee surgery but GM Dave Dombrowski quickly went to Plan B on Saturday. The Sox acquired Brad Ziegler from the Arizona Diamondbacks to bolster the back end of the bullpen for the second-place club.

Two games back of the first-place Baltimore Orioles in the NL east, Boston sits at 48-38 in a tie with Toronto for second in the division as well as the lead for the wild card spot.

It was the third straight day that Dombrowski had made a deal, bringing in infielders Michael Martinez and Aaron Hill previously.

Ziegler has starred in the desert with 18 saves in 20 opportunities this season after a 30-save season in 2015. The Diamondbacks made a big splash in the offseason when they signed Zack Greinke as a free agent, but they currently hold down the cellar of the NL west with a 38-51 record.
