On Pujols Game Used Bats Jeff Scott of Birdbats.com stated " Just because a bat comes with a letter of authenticity ~ even from respected sources like PSA/DNA or MEARS ~ don't go into a purchase blindly. Trust me, the authenticators who sign those letters are nice guys who know their stuff - but they are not watching every at bat, talking with people inside the Cardinals organization or examining virtually every Pujols bat that is offered at auction by the Cardinals. Their letters will tell you a bat is a Pujols model consistent with factory records, and that it is used ~ but they're usually careful not to say that Pujols used the bat.
Frankly, unless he walked from home plate to the stands and handed me the bat personally, I couldn't tell you whether Pujols used a specific bat, either. But, because I do watch every at bat and have examined many actual Pujols bats offered by the Cardinals, I have a much more informed idea of what to look for in a Pujols gamer. Now that you've read this, I hope you do, too".
