Brian Matusz c/o Bowie Baysox - signed one card in blue Sharpie.
Matusz is considered the crown jewel among Baltimore Orioles' pitching prospects and is likely going to be called up - to make his Major League debut on Tuesday.
I was having a cow looking for his 2008 Tristar Prospects Plus card I pulled from this blaster break last year - I found the card in one binder containing several pages of insert cards. The card was with a random Upper Deck USA autograph insert of Matusz I picked up last year.
I sent an autograph request to him and it took about two weeks to get back to me - ironically the Tristar Projections card I sent was replaced with a card from one of Matusz' earlier minor league stops.
I guess that is fine, since Matusz was wearing dark uniform sleeves on the image used for his Tristar Prospects Plus card - and there didn't seem to be much of a light area to sign an autograph on the card.
