Martinez (shoulder) could join the big-league rotation in May or June, Mark Saxon of The Athletic reports.
This is fairly vague, but at least we know we can rule Martinez out for all of April. He is reportedly close to resuming a throwing program, and Jenifer Langosch of MLB.com reports the right-hander recently received a platelet-rich plasma injection to alleviate inflammation. In the meantime, John Gant and Dakota Hudson are the finalists for the fifth spot in the rotation.
