Duda was selected in the seventh round of the 2007 draft by the New York Mets. He's moved up through the Mets' system and is having his best season to date. In 45 games for Binghamton, he hit .286 with 6 home runs and 34 RBI. Since moving up to Buffalo, he is hitting .292 with 5 home runs and 17 RBI. If he continues at anywhere near that pace, he could be in line for a September call-up unless he is part of a trade package before then.
Duda's autograph is a fairly quick scribble, but at least his initials are easily readable.
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.
