What type of pitchers do you struggle to hit against?
I have trouble hitting pitchers who have multiple fast***** (2-seam, palmball, sinker, splitter, moving, cutter, etc.)
The pitchers with three fast***** are the most difficult to face. Anibal Sanchez has a fastball, sinker, and cutter. Jon Lester is another one who has at least three fast*****. If you combine the fast***** with high arm and low control they are near impossible to hit.
Edit: Johnny Cueto is another one.
