"Miller is the crème de la crème as far as prospects go in the Indians system. Last year, Miller was 100% healthy and put up a great season at Akron, going 15-6 with a 2.75 ERA as well as tallying up 161 strikeouts in 158.1 IP. And, in spring training this year, he impressed by throwing 14 shutout innings. Even though his velocity was down a little last year, he still consistently cranks his fastball up to 96 MPH late into games, and this spring he hit 100 MPH in a minor league game. In addition to that, he has developed his secondary pitches and has become more of a pitcher rather than thrower. Miller is the prize of the organization, and with that he likely will be in Buffalo most of the year. Indians General Manager Mark Shapiro has a penchant to coddle his prized-prospects, and when you consider that Miller is not on the Indians 40-man roster it is safe to say that barring a major rash of injuries, Miller won't be in Cleveland until at the earliest as a September call-up."
