Adley Rutschman, Baltimore Orioles
In previous seasons, major league teams had the option to expand rosters to 40 players in September. Unfortunately, added pitching depth to bullpens led to longer games rather than getting a chance to see some young players perform at the big league level. This year, rosters expand from 26 to 28 players plus five taxi squad players while playing away from home.
Baltimore has been out of contention for a long time. However, they have a top-catching prospect who played well over 368 at-bats (.285 with 72 runs, 19 home runs, and 62 RBI) at AA and AAA, who will undoubtedly be in the majors in 2020.
