THURSDAY: Despite the early struggles of Edward Mujica, it doesn’t appear likely that the Red Sox will end up signing Hanrahan, reports Nick Cafardo of the Boston Globe (via Twitter).

WEDNESDAY: The Rockies, Rangers, Red Sox, Yankees and Tigers are among the teams showing strong interest in free agent reliever Joel Hanrahan, reports Jon Heyman of CBS Sports. Hanrahan impressed scouts from as many as 20 teams at a showcase two weeks ago, hitting 93 mph on the gun and appearing to be in good shape. The 32-year-old Hanrahan is roughly two weeks shy of the one-year anniversary of his Tommy John surgery.

The teams listed by Heyman have all seen some degree of bullpen struggles with the exception of the Red Sox, whose collective 3.25 bullpen ERA ranks eighth in the Majors. The other four teams are each in the bottom half of the Majors in terms of reliever ERA, with the Tigers (5.48) and Rangers (4.45) displaying the most troubles in run prevention. Each of the clubs mentioned by Heyman has been relatively stable in the ninth inning to this point, meaning that Hanrahan would likely be ticketed for a setup role should he latch on with any of the five.

Recent reports have indicated that the Mets are also interested in Hanrahan, to an extent, but they aren’t sure whether or not they’ll be making him an offer.
