I am excited to see Zebby Matthews tonight. I don’t see a lot of movement on his fastball from those video clips, but his excellent command of several pitches (according to some reports) may be able to overcome that. The Twins seem to be leaning less and less on fastballs and that has worked to Twins pitchers advantage.
As for the rest, it’s always yet to be seen. Festa looks like just a guy, albeit a great achievement to make it to the majors. I liked Cory Lewis at one point but Lewis needs to get his walks down. Woods Richardson may be the best surprise so far, maybe being in the bigs was actually the best place for him to be and helped him turn that corner. Still too early to be sure with SWR.
I remember wanting PJ Walters, Scott Diamond, and Andrew Albers to be the next big things ten years ago. They were ok for a short time. I was also keen on Jose Berrios and Alex Meyer. I think the best comp for Matthews is probably Bailey Ober—mid round college pitcher with great control. Haven’t dug into it too much.
