In 1964, Carleton students named an intramural slow-pitch softball league after Marv Rotblatt, a former Chicago White Sox pitcher. Although traditional intramural softball is still played at Carleton, the name "Rotblatt" now refers to a campus-wide annual beer softball game that is played with one inning for every year of the school's over 150-year existence. The game begins at sunrise and lasts until the slated number of innings have been completed for that year. The only rule for gameplay is that in order to participate, all players must have a cup in one hand. In 1997, "Sports Illustrated" honored Rotblatt in its "Best of Everything" section with the award, "Longest Intramural Event". Rotblatt himself attended the game several times over the course of his life and appreciated the tradition.
