Here is an exerpt from Chris Kline of Baseball America about Lillibridge:
"No matter how impressive his 2006 numbers were, Lillibridge's year was also somewhat historic, as he was the only player in the minors to hit over .300, post over a .400 on-base percentage, hit over 10 home runs (13), drive in over 50 runs (71) and steal over 50 bases (53)."
As you can see, he does a lot of things well for a shortstop offensively. Lillibridge was rated as the #3 prospect in the Pirates organization by John Sickels who writes an annual book about prospects. Keep in mind, there are also skeptics who wonder if he'll stay at shortstop since he began his collegiate career as a CF with the Washington Huskies and he committed 30 plus errors last season. The anonymous scout in the Baseball America article said Lillibridge was a "poor man's Brian Roberts" which is an indication he probably has a limited ceiling.
