Recently I ran into some articles about the old Princeton tennis coach, Mercer Beasley, who also helped out with the Tigers’ squash teams in the 1930s. The articles were interesting, especially this July 1957 piece from Sports Illustrated:

And the Daily Princetonian:

Yet both of them avoided what was the bizarre and well-known scandal at the heart of the Beasley story. In 1938 Beasley’s wife Audrey famously divorced Beasley to marry his longtime protege and their foster son, Frankie Parker. She was in her forties; he was twenty-two. You hear about coaches getting involved with their players, but less so the coach’s wife.

This might explain what Jack Kramer wrote in his memoirs about how Beasley changed Parker’s forehand for the worse, turning him from topspin to underspin and causing Parker’s ranking to plummet as a result. But Parker went on to be the great U.S. champion of the 1940s. Moreover, apparently everyone was amicable and friendly afterwards, with Beasley sending Parker congratulatory telegrams, and Audrey and Parker remained married until she died in 1971.
