He made Stanton look foolish on 3 pitches, so he did throw some nice sliders today. Nonetheless, if he can't decently command three pitches, he's shouldn't be a swing man. 7th and some 8th inning high leverage situations should where he should be used with the ability to go multiple innings if needed. Either that or obtain another decent pen arm and have Pearson go 3-4 innings per start in Buffalo while he works on his command, especially on his secondaries.
