If making your MLB debut wasn't already a big deal, it just became bigger. Players making their debut in the big leagues will start donning a uniform patch that says “MLB Debut” on their jerseys beginning on Opening Day. These patches will then be added to their Topps rookie cards, creating a new brand of rookie trading cards.
