9 min readOct 26, 2022


The new postseason format in Major League Baseball (MLB) has given us baseball fans a lot of excitement.

Many baseball fans expected the Astros to represent the American League (AL), but few expected the Philadelphia Phillies to represent the National League (NL). However, the MLB postseason has always been presented with randomness.

Still, the game gives us fans excitement. That excitement does not just stem from the game itself, but the players within it. Specifically, the 11 players who played in Division 2 Baseball (D2) and were/are on a postseason roster.

Yes, Major Leaguers can come from D2. Alex Vesia, who appears on this list, said it best,

“People always say you can’t get to the big leagues from Division II. Yes, you can. I’m proof.”

D2 players can make a big impact for teams throughout the regular season and specifically in this article, the postseason.

Let’s breakdown the eleven players (10 pitchers, 1 batter) from nine schools, six conferences, and six MLB teams. This article will go MLB team by MLB team.
