Alyssa Nakken became the first female to be an on-field coach during a Major League Baseball game on Monday night.
Per ESPN.com, Nakken served as the San Francisco Giants first base coach for the final three innings of their exhibition game against the Oakland Athletics.
Nakken made history in February when manager Gabe Kapler hired her as the first female coach for the Giants and first full-time female coach in MLB history.
"Never once did Gabe talk about being the first or even being female," Nakken told NBC Sports Bay Area's Amy Gutierrez when she was hired.
