Last year, the consensus Top 100 prospect list at http://www.attheplate.com/2007/07_rookied.htm included only included 3 2Bs on the entire list in BOS's Dustin Pedroia (who has graduated to the majors), ChC's Eric Patterson (who has played very well and will likely soon start for the Cubs there), & LAD's Blake DeWitt (who has been pretty awful and big league future looks in doubt and he has better 2Bs in his organization). Others that were mentioned for inclusion in our own community rankings were ARI's Alberto Callaspo & MIN's Alexi Casilla.
So, this is a list I've compiled of MiLB 2B or those possibly perceived to play MLB 2B that might actually make an impact...
Eric Patterson CHC (doing great, ETA: soon)
Matt Antonelli SD (great, playing 3B, best 2B?)
Alexi Casilla MIN (MLB, Luis Castillo II?)
Blake DeWitt LAD (does he still count?)
Tony Abreu LAD (playing 3B, hitting well)
Alberto Callaspo ARI (MLB, utility man?)
Mark Reynolds ARI (MLB, playing 3B though)
Emilio Bonifacio ARI (doing ok, longjam @ ARI)
Kevin Frandsen SF (MLB, will start in 2008)
Marcus Sanders SF (will he ever develop?)
Eric Young, Jr. COL (playing poorly)
Corey Wimbley COL (not doing well)
Yung-Chi Chen SEA (surprising, but blocked)
Adrian Cardenas PHI (blocked, doing ok)
Kevin Melillo OAK (taking over for Ellis?)
Scott Sizemore DET(not doing great)
I personally think that, of those listed, Patterson, Casilla, & Antonelli are the cream of the crop right now.
Others??? Guys that might switch (Sean Rodriguez?Longoria?)??? Guys that are emerging??? 2007 draft picks???
