Keep in mind that these groups, especially this first list, are very fluid. Where players are listed now is not likely to be where the player will end up playing the 2010 season for a bunch of these guys.
CLICK HERE to view the 2010 Phillies minor league workout groups. Theoretically Group 1 would be Lehigh Valley, Group 2 would be Reading, Group 3 would be Clearwater, and Group 4 would be Lakewood.
There will eventually be a Group 5 added to the list with Extended Spring Training and Williamsport guys on it as people on this list slide down the rungs over the course of Spring Training. Usually this list is updated each Mondays or Tuesday so I’ll try to post the new list each week as they become available.
