You couldn't ask for a more storybook rookie season than what Buster Posey experienced in 2010. The celebrated catcher joined the Giants in late May and went on to hit .305 in earning National League Rookie of the Year honors. And the cherry on the sundae was his team winning the World Series. That very same year, Posey used this Louisville Slugger M9 maple bat model F156, which features his engraved signature on the barrel. It weighs 34 oz., measures 34", is cracked near the handle and still carries pine tar on the grip. "28" is written on the knob with the manufacturer's date of "12/3/2009." A stunning piece of lumber!
