Zumaya worked out with Barry Zito during the offseason, and one of his points of emphasis upon rejoining the Tigers was raising his arm angle and repeating his delivery. If he can learn to do that, he’ll improve the consistency of his curveball and changeup, both of which are still in the developmental stages. Those secondary pitches will become more important as he progresses through the minors.
He was born on Nov. 9, 1984, and at 18 he’s one of the youngest players in the Midwest League. He’s 6-foot-3, 210 pounds and still growing, so he could add more velocity in time.
