After signing with the Yankees for a substantial bonus, Brown hit .300 in 1947 in 69 games and led the AL in pinch hits (9). The next year he again hit .300 in a career-high 113 games. Because he was a weak fielder, he was platooned at third base and occasionally used at other positions when his potent lefthanded bat was needed. After serving in the military for most of 1952 and all of ’53, he retired from baseball in mid-1954 to practice medicine. He was a hitting star in four WS. His pinch-double tied the seventh game of the 1947 WS, he tripled with the bases loaded in the 1949 WS, and his double led to the only run in Game One of the 1950 WS. In 1984, Brown left a successful career as a surgeon and re-entered baseball as the successor to Lee MacPhail as president of the American League.
