His Hard%, BABIP, LD%, etc, are small samples. They do not have enough data to be relied upon.
His K%, BB%, SwStr%, and GB% are reliable. His K% is below average, his BB% is horrendous, his SwStr is bad but improved over last year by quite a sizable margin, and his GB% is elite.
So, we can surmise that Sanchez doesn't really get strikeouts, walks too many guys, is improving with regards to SwStr but still needs work, and is fantastic at getting GB. This is all we can honestly know about Aaron Sanchez right now.
