Kelly (shoulder) threw an unspecified number of pitches off a mound Thursday, David Vassegh of AM 570 LA Sports reports.
Kelly had thrown from 90 feet over the past two days, and he progressed to mound work Thursday. The right-hander missed the start of camp due to shoulder soreness, but he is now ramping up his throwing program ahead of Cactus League play. Barring any setbacks, Kelly should have enough time to prepare to pitch by the start of the regular season.
