Gilbert (elbow) could be a frontrunner for the Diamondbacks' fifth-starter role, Steve Gilbert of MLB.com reports.
With the top four rotation spots in place, Gilbert and Dan Straily are considered the frontrunners for the final spot. Gilbert made a splash last season as a 27-year-old making his MLB debut, when he tossed a no-hitter against the Padres. He went on to post a 3.15 ERA over nine starts before elbow inflammation ended his season in September.
