The Phillies have undergone massive changes on the field and off over the last couple of seasons.



Those changes have reached the club’s amateur scouting department.



According to major league sources, the club recently fired three longtime members of that department, including Mike Ledna, a high-ranking coordinator and national cross-checker. Ledna was the No. 2 man under former scouting boss Marti Wolever, who was let go two years ago and replaced by Johnny Almaraz.



Almaraz has overseen the last two drafts with a staff of mostly holdover scouts. He has clearly begun to put his stamp on the department with his recent shakeup. Ledna’s firing was preceded by the club’s decision to part with Steve Cohen and Paul Scott. They covered the talent-rich state of Texas.



It is not clear whether more changes on the scouting staff are coming. Over the last year or so, the Phillies have hired a new club president (Andy MacPhail), general manager (Matt Klentak) and manager (Pete Mackanin). The playing roster has also been churned, most recently with Carlos Ruiz being traded to the Dodgers on Thursday (see story). His parting leaves Ryan Howard as the lone member of the 2008 World Series championship team still with the club.
