Nicknamed "Three Finger" because of a farm accident that cost him parts of two of his fingers, Brown used that disability to develop a wicked curveball that went along great with his accuracy. Brown arrived in the city of Chicago from a trade from the St. Louis Cardinals, and in 1906 he moved into the highest tier of hurlers with a 26 and 6 season, and league leading 1.04 ERA and 0.934 WHIP. Brown again won 20 Games in 1907, but this time would pitch the Cubs into a World Series Title and would do so again in 1908. In those two Fall Classics, he would not allow a Run over 20 Innings Pitched.
From 1906 to 1911, Brown was a perennial 20 Game winner and would have a 186 and 86 record and a 1.80 ERA overall as a Cub.Brown entered the Baseball Hall of Fame in 1949 via the Old Timers Committee.
