I would guess these two numbers are the main issue: Stats (AAA): 28 GS, 146.2 IP, 4.66 ERA, 8.8 K/9, 4.8 BB/9, 1.83 K/BB, 3.83 FIP But I would think that even his small sample stint at the MLB level would temper that some, since it was quite a positive step for him: Stats (MLB): 6 G (5 GS), 29.0 IP, 2.48 ERA, 7.14 K/9, 3.4 BB/9, 2.09 K/BB, 2.65 FIP I don't think he damaged his expectations either unless your expectations went in very, very high. His seasonal numbers at AAA are skewed by one horrible month (May) from which he rebounded and he threw the ball very well in the majors. If anything, the fact that he recovered from a bad stretch is a plus and something he can draw on in his career.
