Marcum has been on the 15-day disabled list with biceps tendinitis, retroactive to March 22, but has been rehabbing and tossing from a mound over the past ten days.
The Mets signed him to a guaranteed $4 million dollar deal in January, but he has been injured with one ailment or another since reporting to spring training. It now appears that he is getting healthy and putting all of that behind him. He possibly could join the Mets during their next homestand.
The Mets will not need a fifth starter again until a week from Saturday. Marcum could likely make his Mets debut on that day against the Philadelphia Phillies at Citi Field.
