Born in Remsen, Iowa, Niggeling entered pro baseball in 1928 and promptly won 51 games over his first three minor league seasons.

He had two brief National League trials with the 1938 Bees and 1939 Reds, totaling 42 innings pitched, before he was acquired by the Browns in January 1940. In the American League over the next six seasons, Niggeling would exceed 150 innings pitched each year, win 56 games, and place in the Junior Circuit's top ten pitchers in earned run average three times (–), and strikeouts twice (1942 and 1944).
He won a career-high 15 games with the Browns in 1942 before joining the wartime Senators, who in both 1944 and fielded a starting rotation featuring four knuckleballers (Mickey Haefner, Dutch Leonard and Roger Wolff were the others). Niggeling's career won–lost record was 64–69 with a 3.22 ERA. In his 184 MLB games, 161 as a starting pitcher, he allowed 1,111 hits and 516 bases on balls, with 620 strikeouts, in 1,250 innings of work; he was credited with 81 complete games and 12 shutouts.
