Well, the Twins have gotten a lot of mileage out of Smeltzer. I wonder whether this is the start of his regression to the mean. Actually, all of the starters, except maybe for Bundy, have exceeded both expectations and their batted ball data.
Perez is really both quite a story and quite the enigma. He has had stretches where he has been exceptional and then faded to ordinary. Remembering his time with the Twins, through June he has great numbers and then became ordinary or worse. He had a short successful run with the Red Sox as well and then faded. Now, he has been outstanding through half a season with the Rangers.
