Alyssa Nakken makes history as first woman to field coach in MLB game

San Francisco's Alyssa Nakken on Monday night became the first woman to coach in an on-field capacity during a major league game when she took over as Giants first-base coach. She replaced Antoan Richardson in the late innings of Monday's exhibition at the Oakland Athletics. Nakken joined first-year Giants manager Gabe Kapler's staff in January, becoming the first woman to hold a full-time coaching position at the major league level.
