In Major League Baseball (http://mlb.com http://mlb.com), the season lasts 162 games, from late March/early April to the very end of September. Game 163 is played, only if necessary, as a tiebreaker game (https://en.wikipedia.org/wiki/List_of_Major_League_Baseball_tie-breakers https://en.wikipedia.org/wiki/List_of_Major_League_Baseball_...) that usually determines which team is heading to the postseason and which team is “going home.” Why 162? In 1961, the American League expanded from 8 teams to 10 teams, so instead of playing 154 games against 7 different opponents (22 each), a team now played each other 18 times. (This also works well because 18 is a factor of 3, and baseball often plays its games in a series of 3, held at the same ballpark.) The next year the National League followed suit. If there are any Game 163’s this season they’ll happen Monday.
