Diamondbacks' Jon Duplantier: Set for Double-A debut

Duplantier (hamstring) was activated from the disabled list Saturday and will make his debut for Double-A Jackson, Vince Lara-Cinisomo of MiLB.com reports.

Duplantier's season debut had been delayed by a hamstring injury suffered in spring training, but he's good to go now. The 23-year-old righty profiles as a future mid-rotation starter, with a plus fastball, an array of promising secondaries and average command.
