In advance of tonight's game, the Mets have juggled their active roster again, activating shortstop Ruben Tejada and righty reliever Ramon Ramirez from the disabled list and shifting "infielder" Jordany Valdespin to Triple-A Buffalo. Another move will be forthcoming in order to get the 25-man roster down to, well, 25 players.
Since Friday, the Mets have activated two infielders, Tejada and Ronny Cedeno, which latter rejoined the team for the series opener against the Yankees. The most obvious candidate to settle the roster is Omar Quintanilla, who, after a hot start, is hitting just .185/.241/.222 over his last ten games. His overall line of .273/.368/.394 is still very good for a middle infielder, but given his offensive track record in the majors and minors, it's likely that we've already seen his best efforts with the Mets.
The other possibility for demotion is outfielder/first baseman Vinny Rottino, but that seems less probable since dropping Rottino would leave the Mets with just four outfielders — Lucas Duda, Kirk Nieuwenhuis, Andres Torres, and Scott Hairston — though with Jason Bay seemingly on the cusp of returning to action, there's always a chance the Mets will deal with the outfielder shortfall for a little while.
I've intentionally ignored pitching demotions since the activation of Ramirez would seem to be a corrective to Friday's demotion of Elvin Ramirez, whose loss left the Mets with only eleven pitchers on staff. If they opt to stick with the mighty eleven, Jeremy Hefner is the only obvious candidate for the shuttle to Buffalo.
