He may be ready now. In 17 appearances with Iowa, Ascanio was 1-0 with a 2.08 ERA, nine saves and 23 strikeouts in 21 2/3 innings. He held opponents to a .179 average against -- all in late-inning situations.
Ascanio can touch the upper 90s with his fastball and fills out his repertoire with a changeup and slider.
"His big strength is command of his fastball, which our reports last year had him up to 96 (mph)," Bush said. "He's got a slider that is a developing pitch for him and he's got what is a major league-ready changeup now."
Iowa pitching coach Mike Mason described Ascanio as someone who likes to go with the "hard and slow of it" on the mound, adding that he can be a three-pitch pitcher.
"He also has a two-seam fastball that he really doesn't use when he's in [his rhythm], but he can be a three-pitch guy," Mason said.
