Sportsnet put up an interesting piece on Thomas Hatch today. It's revealed within that the main reason that his control improved so dramatically after his trade to the Jays was that he was suffering through a pretty severe case of shoulder inflammation for a good part of the season. Once he healed up fully he had a dramatic turnaround in his walk numbers at AA for Toronto.

This seems like a guy who is being overlooked by much of the scouting industry. His numbers in New Hampshire are pretty damn impressive, 0.51 BB/9, 2.25 xFIP jump off the page immediately when perusing his numbers. He was hurt a bit by the homerun, but perhaps the 20.8% HR/FB will normalize, previously his high was only 10.4%. It seems he possesses a high spin fastball, effective slider/cutter, and a nice splitter like changeup. What is a realistic ceiling for this guy? I wonder if mid-rotation is attainable by this guy personally, it sounds like he has a lot of good tools at his disposal.
