The main thing is that Fox can be sent to AAA. Guzman is out of options, and there's no way he'd clear waivers. Furthermore, he's still just coming back from TJS. Considering how talented he is, it's worth keeping him around if you have the space for him. Considering how awful Gaudin looked at the end of last year and how terrible he's pitched this Spring Training, I'm hoping the Cubs can find a trading partner for him, send Samardjiza and Fox down to AAA, and keep Guzman and Patton. I'm hoping that they give Patton a shot or work out a trade to keep him. I realize he hasn't pitched above high-A ball, but he has a good arm and has taken full advantage of his opportunity. Gaudin doesn't inspire any confidence with his career 1.52 WHIP. Fortunately, the Cubs are decently stacked in Iowa for the bullpen. If Gaudin is traded or released, Shark can be called up or Fox.
