Who is this? New Hampshire Fisher Cats outfielder Darin Mastroianni What is this? An autographed card from the 2010 New Hampshire Fisher Cats team set Where'd I get it? Mastroianni signed it for me at a Trenton Thunder game this year. How much did it cost? The team set was around $10.
Why is this so special? The Blue Jays selected Mastroianni in the 17th round of the 2007 draft. He spent his second season in New Hampshire in 2010, batting .301 / .390 / .398 in 132 games. Mastroianni has limited power, but good speed - he stole 46 bases in 56 attempts.
Mastroianni doesn't have the prettiest autograph, but to be fair I'd probably look for ways to shorten my signature too if my name was that long.
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.
