And others. Walker wasn't bad in those regards, but not as good.
Does that apply to much of the staying and going youth? Karns couldn't get the walks down. Neither could Montgomery. Might I point you to Max Povse? 0.4 HR/9, 2.0 BB/9 in the minors. Or Nick Neidert at 0.6/1.6.. Or Andrew Moore at 0.6/1.5. Miranda's MiL .7 HR/9 fits but his walks are kind of high as well.
