Lo Duca is scheduled for an MRI today and if all is well he should be back behind the plate on August 27th, when the Mets open up a four game series at Citizens Bank Park against the Phillies. Ramon Castro exited yesterday's game in the third inning with pain in his lower back, so Lo Duca might be missed more than originally thought. Castro is listed as day-to-day and if he does miss any time, look for Mike DeFelice to take the starting catcher job until Castro is able to return.
