It’s surprising because the Yankees just signed J.C. Romero, whom was expected to be called up if they wanted another lefty. It’s also surprising because Garrison has been awful in 46 innings at Double-A this season, putting up a 6.26 ERA. Not sure what the Yankees were thinking on this one, he probably will only serve in mop-up duty.
I doubt anyone will miss Mitre. He’s been awful since his return, perhaps this was the reason why as he actually did well with Milwaukee before they released him.
