The Black Aces are a group of African-American pitchers who have won at least 20 games during a single Major League Baseball (MLB) season. The term comes from the title of a 2007 book by MLB pitcher Mudcat Grant (1935–2021), one of the members of the group. Through the 2023 MLB season, 15 different African-American pitchers have accomplished the feat.

Donald Newcombe, nicknamed "Newk", was an American professional baseball pitcher who played ten non-consecutive seasons in Major League Baseball (MLB). He began his career in the Negro National League and ended it in Nippon Professional Baseball (NPB).
