Lefty reliever Jay Marshall was returned to the Athletics, reported Adam Rubin of the New York Daily News last night. Susan Slusser of the San Francisco Chronicle reports that the A's released Marshall once he was returned.
The Mets had claimed Marshall off waivers from the A's on January 8th, but Rubin says the claim was voided due to a shoulder injury Marshall had at the time of the claim. The A's had designated Marshall in December to make room for Justin Duchscherer. Marshall, 27, posted a 3.20 ERA, 5.3 K/9, and 2.7 BB/9 in 50.6 Triple A innings last year.
