Hello, I’m new to the site but figured someone could help me out here:

My boss (who is a very serious collector of autographs) gave me this. Neither of us have any clue who it is Or if it’s even a baseball player, but he thinks it is. The Baseball is gold edition, with bud selig on it , and says the year “2000” above the MLB logo. PLEASE HELP !! I’ve tried to research but came up with no luck. Thanks guys
