John Wesley Coombs (November 18, 1882 – April 15, 1957), nicknamed "Colby Jack" after his alma mater, was an American professional baseball player.

He played in Major League Baseball as a pitcher for the Philadelphia Athletics (1906–14), Brooklyn Robins (1915–18), and Detroit Tigers (1920).

Born in LeGrand, Iowa, Coombs moved to Kennebunk, Maine with his family at the age of four.

[1][2] Coombs was a 1906 graduate of Colby College in Waterville, where he was a chemistry major and a member of Delta Upsilon.

Three weeks after graduating, Coombs pitched in his first major league game for the Philadelphia Athletics, a seven-hit shutout, defeating the Washington Senators 3–0.

In 1906, he pitched the longest complete game in the American League, 24 innings against Boston, winning 4–1 with 18 strikeouts.

He won 18 of 19 starts that July and racked up 53 consecutive scoreless innings, which stood as the major league record until Walter Johnson broke it three years later.

[3] In 1919, Coombs was the manager of the Philadelphia Phillies for 62 games, going 18–44 before being replaced by Gavvy Cravath.
