Joe Mays, Fransico Lirians, Lester Oliveros, Joe Nathan, Grant Balfour, Pat Neshak, Scott Baker. That is the list of major league Twins to have had the procedure. Matt Bayshore, Mike Fetters, Angel Garcia, Kyle Gibson, Carlos Gutteriz, Jeff Manship, Frank Mata, and Alex Wimmers in the minors. Brian Duensing in college. This was into 2012. Maybe somebody bright with analytics could tell me in what way any of these pitchers were similar in mechanics.
