"Double-A" refers to a classification in the world of minor league baseball, specifically the level of play just below the Triple-A league. It serves as a critical step for players aiming to reach the Major League Baseball (MLB). In Double-A, athletes face more advanced competition, which helps them develop their skills and prepare for the challenges of the MLB. Teams in the Double-A league are often affiliated with MLB franchises, allowing players to be closely monitored by professional scouts and coaches. The level of play is generally considered to be a strong indicator of a player's potential to succeed in the major leagues.
