There is currently a Descalso autographed bat on eBay. It says the bat is game used but I do not believe it was used by Descalso. First problem with it is it is a blonde bat, from all of the pics I have seen and videos he has always used a natural handle, black barrel bat (not counting his 07 card, that may have been a photo bat). Also there is a ball mark where the name usually is and that I do not believe to be common with left handed hitters. I will not be bidding on it. I know he was using Max Bats in 2009 because that is when mine is from and he said that he had not used the ones with silver stickers in awhile. That was last year, He used Max bats with Gold Stickers after that and now uses Marucci.
Gotta watch out with the ads, they say game used, but not by any certain player. Unless it states "used by descalso" i would assume its not used by him.
They had a Descalso bat for 200$ at busch last time i was there. Was SOOO close to picking it up.
