According to David Waldstein of the NY Times, the Mets are trying to void their waiver claim on left-handed pitcher Jay Marshall, who has not reported to camp because of a pre-existing shoulder injury.
Jay Marshall, a left-handed reliever the Mets claimed off waivers from the Oakland Athletics last month, did not report to camp because of a sore shoulder. The Mets said it was a pre-existing injury and asked the commissioner’s office to void the claim
The Mets have good case as last season, while with the Athletics, Marchall had been sidelined due to tendinitis in his throwing shoulder. This offseason the A’s designated him for assignment, and the Mets claimed him on January 8th.
It is now in the hands of the commissioner’s office, who should rule in the Mets favor.
Waldstein also offers another possible reason for the injury and writes,
But with the Mets’ recent history of injuries, this situation sounds more plausible: Marshall was sitting at his home in Missouri on Jan. 8, minding his own business, and the instant the Mets filed the claim, he felt a piercing pain in his throwing shoulder.
