Red Sox signed LHP Mike Holtz, LHP Craig Breslow, LHP Mike Bumatay and LHP Phil Seibel to minor league contracts and invited them to spring training.
Bumatay’s deal was agreed to a couple of months ago, and Breslow agreed to terms last week. The 33-year-old Holtz is back in the U.S. after a year in Japan. He’s not going to be much of a candidate for a spot on Boston’s roster. If the Red Sox carry a lefty reliever, it will likely be Lenny DiNardo.
