#24 Tommy Hanson Rome Braves Atlanta Braves A
Finally a name I recognise. Made his MLB debut for the Braves on the 7th June 2009 vs Milwaukee Brewers.
#162 Justin Jackson GCL Blue Jays Rookie Blue Jays
Justin is currently playing for Dunedin Blue Jays A+.
#142 Hector Correa Jameston Jammers Florida Marlins SS
Acquired by San Francisco Giants from Florida in exchange for Ronny Paulino on March 27, 2009. Currently playing for the AA Richmond Flying Squirrels. I wonder if Bullwinkle is a mascot?
# 109 Danny Rams GCL Twins Rookie Minnesota Twins
Still with the Twins affiliation and currently playing with A+ Fort Myers Miracle
#189 John Mayberry Jr. Frisco Roughriders AA Texas Rangers.
Another fantastic club name 'roughriders'. John Jr.was traded to the Philadelphia Phillies in Nov 2008 for Greg Goulson and made his MLB debut on the 23rd May 2009 vs Yankees. His father John Mayberry Snr. was a first basebman for the Astros, Royals, Blue Jays and Yankees between 1968 and 1982.
So out of a pack of 8 prospects, 3 have advanced to a MLB debut, 4 are still playing Minor league ball and 1 has left baseball altogether because of ill health. That sounds like a pretty good ratio, however I don't know the percentage of Minor League players that advance further than AAA.
