Lewis Albert Fonseca (January 21, 1899 – November 26, 1989) was an American first baseman, second baseman and manager in Major League Baseball for the Cincinnati Reds, Philadelphia Phillies, Cleveland Indians, and Chicago White Sox. While not a power hitter, he hit for average and was a good contact hitter for most of his career. He topped the .300 mark six times, with his best season coming in 1929 with the Indians, when he hit .369 to win the American League batting title, after coming off a 1928 season in which he broke his leg. His success was short-lived, however, as he broke his arm in 1930, and a torn ligament in his leg prematurely ended his playing career.
