There's no "there there" with him. His fastball is flat and he has zero command on it. His breaking ball is essentially a show me pitch. His changeup? Ha, there are high school pitchers with better changeups.
While the White Sox have holistically done a helluva job rebuilding they continue to have a weak spot when it comes to over holding failed players. Reylo simply is not a MLB pitcher at the moment. Maybe a miracle happens and he becomes one on Saturday but wish in one hand and shit in the other and see what fills up first. It's fine to trot out guys like Reylo and Covey when you aren't contending but not anymore.
I guess this is why Gio pitched the other night? Or not? Like, what was the point of that move relative to this one? I'm honestly curious. I figured they were trying to get him stretched out a bit so he could start Saturday and go 3-5 innings. Just puzzling moves. I guess after Reylo inevitably runs into trouble in the first 4 innings, Gio will be called on to try and mop up.
