Buster Posey, the fifth overall pick in the June amateur draft, gets the largest up-front bonus in major league history when he agrees to a $6.2 million signing deal with the Giants. The highly touted catcher gets slightly more than infielders Tim Beckham (first pick/shortstop), who receives $6.15 million from the Rays, and Pedro Alvarez (second pick/third baseman), who gets $6 million from the Pirates.
