Duplantier combines a quality repertoire with outstanding control and impressive command. He is a no-doubt starter, possessing a desirable build and fairly clean mechanics. He locates his fastball well, making him averse to walks and often putting himself in favorable counts. His feel for his secondary offerings can waver, and he presently lacks a true out pitch, but he mixes his offerings and can place them well enough to generate swings and misses. Duplantier has had both shoulder and elbow injuries in the past, but neither required surgery and he has shown no ill-affects this year. Ultimately, Duplantier offers a high probability of being a fourth starter in the majors thanks to advanced his advanced control and fastball command, with a chance of becoming a high-three starter if the feel for his secondary offerings develops well.
