On January 21, 1947, Day traveled to Juarez, Mexico, where she received a second divorce decree. Later that day, she traveled to El Paso, Texas, where she married baseball manager Leo Durocher. Upon returning to California, the judge who granted Day's interlocutory divorce from Hendricks stated that the Mexican divorce she received was not legal and, since she failed to wait the one-year period for her divorce to become final, deemed her Texas marriage illegal as well. After waiting about a year, Day and Durocher remarried on February 16, 1948, in Santa Monica, California. After the couple moved to New York, Day read every book about baseball she could to understand the game. She became the first woman to be honored by the New York chapter of the Baseball Writers Association at their annual dinner in 1951. During her marriage to Durocher, Day was often referred to as "The First Lady of Baseball". While Durocher was managing the New York Giants, she wrote the book "Day With the Giants" (1952). She was also the host of "Day With the Giants", a 15-minute television interview program broadcast before New York Giants home games. Day and Durocher divorced in June 1960.
