Single-A Baseball

Single-A follows standard Major League Baseball rules with modifications for player development and pace of play. The season runs from early April through mid-September, with teams playing 132 games. Rosters are set at 28 players. A pitch clock is enforced at 15 seconds with bases empty and 20 seconds with runners on. The designated hitter is used universally. Each of the three leagues (Carolina, Florida State, and California) conducts its own playoff tournament, typically featuring best-of-three series. Players at Single-A are overwhelmingly young prospects in the early stages of their professional careers, most of whom are not yet on their organization's 40-man roster. Development takes priority at this level, and organizations may manage workloads by limiting innings for young pitchers or rotating position players through multiple defensive positions.
