Robert Moses "Lefty" Grove (March 6, 1900 – May 22, 1975) was a professional baseball pitcher. After having success in the minor leagues during the early 1920s, Grove became a star in Major League Baseball with the American League's Philadelphia Athletics and Boston Red Sox, winning 300 games in his 17-year MLB career. He was elected to the National Baseball Hall of Fame in 1947.
One of the greatest left-handed pitchers in major league history, Grove led the American League in wins in four separate seasons, in strikeouts seven years in a row, and had the league's lowest earned run average a record nine times. Over the course of the three years from 1929 to 1931 he twice won the pitcher's Triple Crown, leading the league in wins, strikeouts, and ERA, while amassing a 79-15 record as the ace for the Athletics' dynasty teams.
Born in Lonaconing, Maryland, Grove was a sandlot star in the Baltimore area during the 1910s. In 1920, he made his professional debut with the Martinsburg Mountaineers of the class-D Blue Ridge League, where he appeared in six games. In 59 innings pitched, Grove gave up just 30 hits, and he had an earned run average (ERA) of 1.68. His performance attracted the attention of Jack Dunn, the owner of the minor league Baltimore Orioles, who also discovered Babe Ruth.
