Cautious optimism, but when youre 24 in High A and as recently as last season walked 7 per 9 at the same level, it's hard to get see that he might be a pen guy some day. Should he get bumped up to AA and retain those his current K and BB rates, then you're maybe looking at a guy who might make it.
That said, improving from a BB/9 of 7, to under 2 is nice to see.
