As expected, the Mets have activated shortstop Ronny Cedeno for tonight's series-opener against the Yankees at Citi Field. Cedeno had been rehabbing a strained left calf, getting back to playing shape with Triple-A Buffalo this week. Before the injury, which was originally diagnosed as a day-to-day leg cramp, Cedeno was hitting .231/.351/.308 with a home run, two doubles, and eleven walks.

To make room for Cedeno, the Mets have optioned right-handed reliever Elvin Ramirez to Buffalo. Ramirez had allowed eight walks, eleven hits, and seven runs in seven innings. The Mets will be down a reliever for at least one game.

With the left-handed Andy Pettitte on the mound for the Yankees tonight, the Mets are wasting no time throwing Cedeno back into action. He'll be playing shortstop and batting second. Omar Quintanilla, who got off to a hot start with the Mets but is hitting .167/.219/.167 over his last ten games, will get the night off.
