So I'm currently in the market for a Jeter game used bat and there's one I could get that has a birth date on the knob from mid march of 2011. now obviously, a bat used during the regular season has more value than a bat used during spring training, but how between the bats birth date, when does it usually go into circulation of being used in a game for a player? im sure jeter goes through a few bats during the season including pre and post season, but do you think a bat with the date from mid march wouldve been used in the regular season?
