http://insider.espn.go.com/mlb/story/_/id/6849816/mlb-2011-draft-prospects-already-signed Top signed prospects from 2011 draft Catcher: Neftali Rosario, Chicago Cubs A sixth-round pick out of the Puerto Rico Baseball Academy, Rosario's $150,000 bonus is one of the biggest in the round. The 18-year-old has lived up to expectations by showing excellent receiving skills with a plus arm while surprising with his bat, hitting .340/.375/.566 in limited action for the Cubs complex team in Arizona. He might not be ready for a full-season assignment in 2012, but this summer's performance gives him a better chance to do so.
