Wolf doesn't have an overpowering fastball. At first glance, it doesn't look like he has the stuff to even succeed at the major league level. I think that's why he's underrated and will always be so, however the boy sure does have a good slow curve and knows how to pitch. He is like a Moyer or Rueter but with strong K potential.
