After a short stint with the
St. Louis Giants, he entered the NNL with the
St. Louis Stars in 1924, playing for the Stars through 1931, when both the team and league folded after the 1931 season. In 1926 he hit 27
home runs, a Negro leagues single-season record. In 1930, he led the Negro National League in home runs (seventeen), runs batted in (114), and batting average (.411) to win the batting Triple Crown; he was the fourth player to achieve the distinction. From 1932 to 1935 he played for the
Chicago American Giants and played for the
Newark Eagles from 1936 to 1939. While with the Eagles, Wells was part of the "Million Dollar Infield," consisting of Wells,
Ray Dandridge,
Dick Seay, and
Mule Suttles. He played in
Mexico in 1940 and 1941, where he said he experienced democracy, acceptance and freedom. Wells was nicknamed
El Diablo by Mexican fans for his extraordinary intensity and the English translation ("The Devil") followed him as a nickname in the United States. He returned to the Negro leagues in 1942 as a player-manager for the Eagles and then went back to Mexico for the 1943 and 1944 seasons. Returning to the U.S. in 1945, Wells played for various Negro league teams through the 1950 season, including the
Memphis Red Sox where he played alongside his son
Willie Wells Jr. in 1948. He then went to
Canada as a
player-manager for the Winnipeg Buffaloes of the
Western Canadian Baseball League, remaining there until his retirement from actively playing baseball in 1954. Wells returned to the U.S. and continued as the manager of the
Birmingham Black Barons. ==Later life and legacy==
