In the late 1950s, Mr. Rotblatt settled down and embarked on a career selling insurance for New England Life. He spent 39 years with the company, retiring in the 1990s, his son said.
In 1964, students at Carleton College in Northfield, Minn., began putting Mr. Rotblatt's name on an intramural softball league, it was said, after a student had one of Mr. Rotblatt's old baseball cards.
Three years later — and every year since — students have played a marathon softball game named after Mr. Rotblatt that runs from sunrise until sunset. The rules of the game require players to use just one hand to hit and field, often carrying a beer in the other.

    One year, Mr. Rotblatt brought three bats up to the plate and swung them around in "a vaudeville thing," his son said. He then returned to the plate with one bat, pointed to the outfield in true Babe Ruth fashion and slugged a home run.

    Mr. Rotblatt mostly lived in the Chicago area after his major league career, although he moved out to Las Vegas for a time in the 1990s. After experiencing some health problems, he returned to Skokie in 2000, his son said.
