You can never have too much pitching depth, and the Boston Red Sox are beginning to load up.
According to USA Today's Bob Nightengale, the Red Sox are signing veteran reliever Kevin McCarthy to a minor league deal.
McCarthy appeared in just five games last season with the Royals but had at least 55 appearances in each of the previous two campaigns. He'll finish his run with the Royals with an 11-6 record and 3.80 ERA over 191 2/3 innings (169 appearances, all in relief).
It's unclear if the 28-year-old's deal comes with an invite to big league spring training.
