Big thing for him this year will be to stop throwing so many ball fours. Also will be interesting to see how all these hard throwers adjust to the majors after pitching just 80-100 IP a year in the minors like he, Susana, Syroka, and other teams' young prospects are. If MLB starters start going less than 5 IP, and can't get through the lineup twice, their value will plummet.
