Baseball Almanac presents the Major League teams who have lost more than one-hundred ten games in a season in order by most games lost (with links to rosters, stats & schedule):
On September 7, 1896, the Louisville Colonels lost all three games of a tripleheader. On September 8, 1896 they lost both games of a doubleheader making them the only team in Major League history to lose five games in two consecutive days.
Did you know that the 1950 Chicago Cubs lost a Major League record nineteen doubleheaders? Too easy? Did you know that 1968 Chicago White Sox lost a Major League record forty-four one run games? Still too easy? Did you know that the 1980 Seattle Mariners lost a Major League record eighty-three night games?
