STATE COLLEGE, Pa. -- Mitch Keller will return to the big leagues Monday in Anaheim, Calif., as he'll makes his fourth start for the Pirates, his first since June 18.
Perhaps now, after putting together a solid body of work since going back down to Class AAA Indianapolis, Keller will finally be ready to show off his curveball a bit more. In his three previous big-league starts, Keller three 106 four-seam fastballs, 35 sliders and just 15 curveballs. Eight changeups were thrown in for good measure.
Having just added a slider this season, it should come as no surprise that Keller is utilizing it more, to figure out its viability both in the minors and the majors. Still, the curveball has always been considered to be his second-best pitch behind his fastball. So why hasn't he shown it a bit more?
