<P> The regular season is constructed from series . Due to travel concerns and the sheer number of games , pairs of teams are never scheduled to play single games against each other ( except in the instance of making up a postponed game ) ; instead they play games on several consecutive days in the same ballpark . Most often the series are of three or four games , but two - game series are also scheduled . Teams play one mid-week series and one weekend series per week . Depending on the length of the series , mid-week series games are usually scheduled between Monday and Thursday , while weekend games are scheduled between Thursday and Monday . Beginning in 2018 , teams start and end their season on a weekend for a total of 261⁄2 weeks . Due to the mid-week all - star break in July , teams are scheduled to play 27 weekend series and 25 mid-week series for a total of 52 series ( 24 divisional series , 20 inter-divisional series , 8 inter-league series ) . A team 's road games are usually grouped into a multi-series road trip ; home series are grouped into homestands . </P>
