William Henry Keeler (March 3, 1872 - January 1, 1923) in Brooklyn, New York, nicknamed "Wee Willie", was a right fielder in professional baseball who played from 1892 to 1910, primarily for the Baltimore Orioles and Brooklyn Superbas in the National League, and the New York Highlanders in the American League.
Keeler was a remarkable hitter, whose advice to hitters was, "Keep your eye clear, and hit 'em where they ain't" -- "they" being the opposing fielders.
K is for Keeler,
As fresh as green paint;
The firstest and mostest
To hit where they ain't.
