A 6 ft (1.83 m), 187 lb (85 kg) right-hander, he played all or part of eight seasons in Major League Baseball (MLB) for the Washington Senators (1943–44; 1946–49) and Philadelphia Phillies (1950–51).

After four standout appearances as a relief pitcher, allowing no runs and five hits in 101⁄3 innings pitched, he received his first starting assignment June 2 against the Cleveland Indians.

He continued to pitch effectively until the end of July, and then came back to the pack with some poor outings mixed in with four more complete games during August and September.

His rookie 1943 season, which would be his finest in the Majors, ended with an 11–7 record, a 2.49 earned run average (sixth in the American League), eight complete games and three shutouts.

He got into 18 games, all in relief, for the 1950 Phillies and won his only decision, July 26 against the Chicago Cubs, but his lone win contributed to the "Whiz Kids"' narrow triumph in the National League (NL) pennant race that season.
