How much did it cost? You'd have to check with Zach.
Why is this so special? Lenny DiNardo began his pro career in the Mets' minor league system, but the Boston Red Sox selected him in the Rule V Draft prior to the 2004 season. They managed to keep him on their roster throughout the whole season, so they got to keep him and he earned a World Series ring.
DiNardo played in a few games for the Red Sox in 2005 and 2006, but he spent more time in the minors. During spring training in 2007, Oakland claimed DiNardo on waivers. They used him as a starter for a bit more than half of the season, but he also worked out of the bullpen. DiNardo remained in Oakland in 2008, but signed with the Royals for 2009. This year, he's back in Oakland's system again.
DiNardo has been a member of Italy's team in both the 2006 and 2009 World Baseball Classics.
I'm very happy that I do not have to try to read Lenny DiNardo's handwriting.
I'm only putting autograph-related links in this blogroll. However, if you have a blog or a collector site not specifically about autographs, but with an autograph page or an "autograph" label on your blog posts, I'll put that link here.
