Monday Night Baseball was a live game telecast of Major League Baseball that aired on Monday nights during the regular season. These games formerly aired weekly on ESPN. The game started at 7 p.m. ET, following SportsCenter, and usually lasted around three hours leading up to an hour-long Baseball Tonight. The program sometimes aired on ESPN2 rather than ESPN, often due to NBA playoff coverage in April and May, and preseason Monday Night Football coverage in August. Earlier incarnations of Monday Night Baseball aired on NBC and then ABC in the 1970s and '80s.
