Former Royal, Rookie of the Year, Dodger, YankeeAstute observers of the New York Mets may have noticed that Argenis Reyes was demoted to AAA Buffalo at the beginning of the All-Star break, but that no corresponding move was made to replace him.   Well the cat is out of the bag.   New York Mets Vice President of Development Tony Bernazard, appearing as a guest on SNY's broadcast of tonight's Williamsport Crosscutters-Brooklyn Cyclones game, noted that Angel Berroa would be joining the Mets in Atlanta when the regular season resumes there Thursday night, putting to rest fears that due to the recent news the Wilpons may have lost as much as $700,000,000 to Bernie Madoff's ponzi scheme the Mets were going to proceed with a 24 man roster.
