2021 MLB Debut Chart With Signing Scouts



Because of the coronavirus pandemic, many things were strange about the 2020 big league season. Foremost among those quirks was the number of players who debuted despite the regular season being just 60 games long (or 61, if you're Starling Marte). In total, 212 players got their first taste of the big leagues. 

Three of those players—Minnesota's Alex Kirilloff, Tampa Bay's Shane McClanahan and San Diego's Ryan Weathers—made their debuts during the postseason, leaving 209 during the stunted regular year. 

By comparison, 261 players debuted during the 162-game regular season in 2019. 

Last year, Baseball America decided to keep track of who debuted and when, with credit to each player's signing scout. You can find the 2020 version here. 

We're doing it again in 2021 starting the day after Opening Day, which saw nine new big leaguers. That list includes top prospects like Jonathan India (Reds), Ha-Seong Kim (Padres) and Taylor Trammell (Mariners) as well as Rule 5 draftees Will Vest (Mariners) and Brett de Geus (Rangers). 

Keep an eye on this page all season long for an updated list.
