This is a piece of a game used bat swung by Colby Rasmus! The bat is a Louisville Slugger B363. This piece comes from a bat that was broken during Colby's 2009 rookie season. This section of the bat has Colby's name/signature stamped into the wood in silver lettering. The piece is from the trade mark of the bat to the end of the barrel. Colby has signed this bat in silver Sharpie and it reads, "Colby Rasmus 28". This was authenticated by JSA on 4/7/2011.
