While going through the MLB Auctions website for Mets stuff I was surprised to find the following item up for bids:
Game Used Baseball - [NYM] Rafael Montero to [NYY] Brett Gardner - First Career Pitch - 1st Inning - Mets vs. Yankees - 5/14/14 - EK702627
The very first baseball ever thrown by a Major League pitcher in his career, authenticated and documented. This was a first for me. I've seen game-used baseballs FROM from a pitcher's first game (at last year's MLB Fan Fest MLB was asking $1,000 for a GU ball from Matt Harvey's debut, but that's got to be an extreme case) - but a first pitch, never. It was also surprising to me that the auction began just a week after Montero's debut.
The ball sold for $510.01.
