Mlb: 10 Youngest Players to Ever Debut in Big Leagues

While 19-year-olds are regularly the youngest age an MLB player can make his debut, it has been rare to see anyone younger showcase his talent on the MLB field. In fact, the last 18-year old to make his MLB debut was Alex Rodriguez which was way back in 1994. Furthermore, while Jasson Dominguez is a top young prospect, his highly anticipated MLB debut will still come in 2023.

Although teenagers younger than 19 have been rare in the MLB, some have managed to accomplish this feat with a lot of them being called up due to the World War. For this piece, let’s take a closer look at the 10 youngest players to ever debut in MLB.
