When Does Fantasy Baseball Start in 2025?

By Sarah Miller · June 19, 2049

Fantasy baseball typically starts in late March or early April, aligning with the official Major League Baseball (MLB) regular season opening. For the 2025 season, fantasy leagues are expected to begin their drafts in mid-March, with most platforms setting the first week of gameplay to start around March 27, 2025, depending on league settings and draft timing.

When Does Fantasy Baseball Start in 2025?

The fantasy baseball season closely follows the MLB calendar. In 2025, MLB’s regular season is scheduled to begin on Thursday, March 27, with a marquee matchup between the Los Angeles Dodgers and the New York Yankees in Tokyo, Japan. As a result, fantasy baseball leagues on major platforms like ESPN, Yahoo, and Sleeper will officially kick off around that date.

Most fantasy managers begin preparing weeks in advance by participating in mock drafts, analyzing player projections, and finalizing rosters. The primary draft window for seasonal leagues runs from mid-March through the end of March, allowing players to set their lineups before Opening Day.
