2) Red Sox pitcher Justin Garza will not be on the roster past June 1
You know how it is, relievers with options are always on the carousel back and forth between AAA and the majors. The only relievers with options on the roster right now are Josh Winckowski, Kutter Crawford, and Justin Garza. Winckowski has been one of Boston's best relievers so he's not going anywhere. Crawford has been effective in long relief, he's likely not going anywhere. When Boston needs a fresh arm, Garza is likely the odd-man out.
While they've been better in this category lately, Boston starters don't go very deep into games. Red Sox relievers have thrown the 12th most innings in baseball. Eventually, a starter won't go very deep, the bullpen will be exhausted, and they'll need a fresh arm. Garza is the easiest to let go of.
The right-hander was picked up off of waivers from the Los Angeles Angels. In his two appearances this season for Boston he's pitched two scoreless innings without allowing a baserunner. These appearances came on back-to-back days against Seattle in the ninth in games that were practically over.
Boston claimed Garza for a reason, so he won't be in the minors all season. He has options, and the Red Sox, like every other team, will plan to take advantage of that while they can. There isn't too much value in holding a one-inning reliever who only pitches in blowout situations anyway. This loss won't be as big of a deal as Bello or the next guy.
