A 6-foot-4 lefty from Hawaii who was first ranked as a top 400 prospect back in 2018, Cantillo posted some intriguing metrics (31.1 Whiff%, 27.0 K%, 48.1 GB%, 99th percentile extension) across 38.2 innings last season working primarily as a starter for the Guardians. He had a 4.17 FIP, 3.45 xFIP and 17.7 K-BB% in eight starts, although his surface stats were less glowing (5.11 ERA 1.35 WHIP). His elite extension and slightly above-average induced vertical break allow his 92.2 mph four-seamer to play up, while his changeup and curveball will flash plus. His run in the majors was the first time Cantillo logged a walk rate below 10 percent above rookie ball since he was at Single-A in 2019, and he doesn't have much margin for error if his fastball once again sits in the low-90s. Still, Cantillo figures to open the year in the rotation for a good team with a good defense in a pitcher-friendly park, and there were enough encouraging signs last year to buy him as a cheap breakout candidate.
