Alcantara showed glimpses of his considerable upside across six starts with the big league club last year. His control and pitchability must continue to refine, but the swing-and-miss stuff is here to impact a rotation. The best-case outcome is a power mid-rotation starter who racks up gaudy strikeout totals on the strength of a high-90s fastball, above-average curve, and workable changeup. There’s some reliever risk, but he showed us enough last year that we’re in on Alcantara the starter. Expect to see him vying for time in the Major League rotation in 2019.
