Diamondbacks' Merrill Kelly: Features changeup in second start

Kelly allowed two runs on five hits and struck out four over three innings in Wednesday's spring start against the Rockies.

Kelly emptied the entire arsenal of pitches Wednesday, throwing 47 overall. He worked on his changeup leading up to his second Cactus League start, after featuring a developing slider the first time out. "I've thrown my changeup for a long time now, it's kind of been the pitch that I've gone to when I needed something," Kelly told Alex Weiner of Arizona Sports. "The slider is obviously something that I want to make more consistent and more into a usable pitch, so the emphasis coming into spring was on the slider and sometimes when you do that the feel for the rest of the pitches kind of isn't as sharp." Kelly will get two more starts to work up to 75-80 pitches before the regular season opens.
