Negro American League

Major league prior to 1950; minor league after 1950.

• 1937: Formation of NAL consisting of 8 teams — Birmingham Black Barons, Chicago American Giants, Cincinnati Tigers, Detroit Stars (III), Indianapolis Athletics, Kansas City Monarchs, Memphis Red Sox and St. Louis Stars (II).
• 1938: Dropped Cincinnati Tigers, Detroit Stars (III), Indianapolis Athletics and St. Louis Stars (II); Added Atlanta Black Crackers, Indianapolis ABCs (II) and Jacksonville Red Caps.

From 1939 through 1942 and 1944 through 1947, the team in first place at the end of the season was declared the Pennant winner. Due to the unorthodox nature of the schedule (and little incentive to enforce it), some teams frequently played many more games than others did in any given season. This led to some disputed championships and two teams claiming the title. Generally, the team with the best winning percentage (with some minimum number of games played) was awarded the Pennant, but other times it was the team with the most victories. The "games behind" method of recording standings was uncommon in most black leagues.

• 1937 Kansas City Monarchs†, Monarchs awarded first-half championship but Chicago American Giants had better record and disputed it, no second half of the season was recorded and Kansas City was awarded the Pennant.
• 1938 Memphis Red Sox†
• 1939 Kansas City Monarchs
• 1940 Kansas City Monarchs
• 1941 Kansas City Monarchs

• 1945 Cleveland Buckeyes‡
• 1946 Kansas City Monarchs‡

† – Pennant was decided via a split-season schedule with the winner of the first half of the season playing the winner of the second half of the season.

From 1937 through 1938, and again in 1943 and 1948, the NAL split the season into two halves. The winner of the first half played the winner of the second half for the league Pennant. As mentioned above, disputes also occurred in the split season finishes.

• 1937 – Kansas City Monarchs (first half champions), second half not documented
• 1938 – Memphis Red Sox (1st half) over Atlanta Black Crackers (2nd half), contested play-off declared "no contest" after Memphis up 2 games to 0 games
• 1943 – Birmingham Black Barons (one half) beat Chicago American Giants (one half), 3 games to 2 games
• 1948 – Birmingham Black Barons (1st half) beat Kansas City Monarchs (2nd half), 3 games to 1 game
