The Mets are facing another injury issue, this time with reliever Jay Marshall.
Marshall, a left-hander the Mets claimed from the Oakland A's off the waiver wire in January, has not shown up at Spring Training camp in Port St. Lucie, Fla., because of a sore shoulder that the Mets say was a preexisting injury.
The Mets have asked the Commissioner's Office to void the claim and that the office is investigating the matter, because injured players should not be put on waivers.
Marshall, who compiled a 7.66 ERA in 68 games with Oakland in the 2007 and 2009 seasons, joins Kelvim Escobar as the second Mets relief pitcher to have shoulder problems early in the spring. Escobar, who signed a Minor League deal, is still attempting to recover from shoulder woes that have limited him to one game since the end of the 2007 season.
