Frank Angelo Joseph "Creepy" Crespi (February 16, 1918 – March 1, 1990) was a Major League Baseball player who played infielder from 1938-1942 for the St. Louis Cardinals.

In 1951, longtime Cardinals star shortstop Marty Marion praised Crespi as the best defensive second baseman he'd ever played with.

Though he qualified for a deferment as the sole supporter of his elderly mother, he refused, claiming, "I don't think I'm too good to fight for the things I've always enjoyed.

"[4] During an Army baseball game in Kansas, he suffered a compound fracture of his left leg while turning a double play.

[5] While he was recuperating at the hospital, a nurse accidentally applied 100 times the appropriate quantity of boric acid to his bandages, causing severe burns on Crespi's leg and leaving him with a permanent limp.
