While most people talk about Posey's bat, and for good reason, it should be noted he threw out 46 percent of would-be basestealers in 2009. And he didn't really take a step back when he jumped from Class A Advanced up to Triple-A. With San Jose, he threw out 49.2 percent; in Fresno, it fell only to 38.1.
Scouting report: Equipped with perhaps the best, and most advanced, hitting approach of anyone on this list, Posey can hit to all fields. While not a huge power guy, he's got plenty of extra-base pop, and could hit 15-20 HR a year in the bigs. A very good athlete who used to play shortstop, he runs very well for a catcher and has a plus throwing arm. He's still learning the nuances of playing behind the plate full-time.
Upside potential: An every-day catcher with star potential at the big-league level. The bat is ready to contribute right now if given the chance.
They said it: "He wants to learn, get better and be a key aspect in winning a championship. The best thing you can say about a kid is that he's a 'gamer,' and that's Buster Posey." -- Andy Skeels, Posey's manager in San Jose in 2009
He said it: "I'm even more happy to be on a team fighting for a playoff spot. I'm looking forward to the atmosphere." -- After getting called up to the big leagues last September
