The Peoria Javelinas roster can be found here.
Looks like the group so far is...
RHP Stephen Kahn
RHP Kam Mickolio
RHP Joe Woerman
C Jeff Clement
2B Yung-chi Chen
3B Matt Tuiasosopo
... with one more pitcher still to be named.
The roster may change a bit before the season starts. since all of these guys are above double-A, they still have the option to use the last spot for someone below double-A, but I have no guesses as to who that might be at this point.
