The Philadelphia Daily News reports Cesar Hernandez has been optioned to Double-A Reading to get more reps in center field during the All-Star break. Hernandez has been primarily a second baseman with Triple-A Lehigh Valley this season, but could be an option to replace Ben Revere (foot) in center field. John Mayberry will continue to get the majority of starts for now. Phillies GM Ruben Amaro is expected to be looking for outfield help at the July 31 trade deadline.
