He was well known at Florida State where he played all nine positions (in one game!), but was mainly a catcher. He led the nation in batting average, hits, RBI, and slugging percentage, while leading Florida State to their first College World Series appearance since 2000. He won all of the top awards in his final year at FSU, including the Golden Spikes Award, the Dick Howser Trophy, the Johnny Bench Award, and a few more. Florida State's trip to the CWS was brief, but it was just the beginning of Posey's career.
He was drafted fifth overall in the 2008 draft by the San Francisco Giants, and received a $6.2 million bonus, the largest up-front bonus in MLB draft history at the time. So far Posey has made the Giants look like geniuses for giving him the rather large signing bonus.
He has been tearing it up for the San Francisco Giants Class A Affiliate San Jose Giants. He's near the top in almost every statistical category. He's seventh in the California league with 11 home runs in 244 at-bats. He also has 48 RBI's to go with 50 runs scored. He's shown good plate discipline with 36 walks and 39 strikeouts and might soon be getting promoted.
His promotion however would not be to Double-A. The talks right now are that he will be promoted directly to Triple-A. Giants manager, Bruce Bochy, feels that Posey will learn quicker by catching for guys who have made it to the MLB before.
Don't go pick him up in your fantasy league just yet though. The plans are to keep him in the minors for the entire year, but expect him to make a huge impact for the Giants next season.
