Day's marriage to Durocher, in 1947, landed her in a newspaper front-page soap opera that lasted for months. She married Durocher in Texas, one day after being granted an interlocutory decree — a temporary court order, now seldom used — setting forth terms of divorce from her first husband, the singer Ray Hendricks, in California. Because that divorce would not be final for a year, a California superior court judge tried to revoke it, citing "collusion and fraud." The solution, months later, allowed her to stay married in 47 of the 48 states in the union at the time but ruled that cohabiting with her new husband in California would be bigamy.

In 1946, Day had signed a contract at RKO for one picture a year for five years at a salary of $100,000 per movie, but only two films were made. She played a psychopathic killer in "The Locket" (1946) and a rich girl who is disinherited when she marries the railroad builder John Wayne in "Tycoon." Her last major film role was in "The High and the Mighty" (1954), an early airplane disaster movie.

Day's survivors include two daughters with Grilikhes, Dana Grilikhes Nassi and Bell; and a son and daughter with Durocher, Christopher and Michelle; her twin brother, Lamar, of Chico, Calif., and numerous grandchildren.

During her marriage to Durocher (who died in 1991), she was the host of "Day With the Giants," a 15-minute television interview program broadcast along with New York Giants home games. She also published a memoir, also titled "Day With the Giants." After her divorce from Durocher in 1960, she told an interviewer that she had never liked baseball. "When our relationship was over, so was my relationship with baseball," she said.
