Lobert went on to be the baseball coach of the United States Military Academy at West Point with the help of McGraw. He later served as McGraw's full-time scout and eventually become a coach for the New York Giants in 1928. Lobert became the manager of the Eastern League's Bridgeport team, the next year. He then managed the Jersey City team of the International League. After managing in the minor leagues during the 1920s and early 1930s, Lobert became a coach for the Phillies from 1934 through 1941. At 60, he became one of the oldest rookie managers in baseball history when he was appointed skipper of the 1942 Phils, in the midst of the longest streak of futility in their history. Under Lobert, the club lost 109 games (they had lost 111 under Doc Prothro in 1941). Counting two losses as an interim manager in 1938, Lobert's career managerial record was 42–111 (.275).
