2020 MLB Debut Chart With Signing Scouts
Because of the strange, stunted nature of the 2020 season, there were a lot more big league debuts than would typically be seen through the first third of the season. All told, 209 players got their first tastes of the majors this year. By comparison, 261 players debuted in all of 2019.
Here, we present all of the debuts—thanks to the folks at Baseball Reference for tracking them—along with each player's signing scout(s). This chart will be updated throughout the course of the rest of the season.
