 Biographical Information
Tornado Jake Weimer has one of the lowest ERA's in major league history. In seven seasons in the majors, he posted a 2.23 ERA, twelfth-best of all time. He also won 20 games three times.
According to an article in the July 12, 1908 New York Times, when Weimer was traded from Cincinnati to New York, he refused to report unless he was paid half of the money involved in the deal. He said that otherwise he would leave baseball and go into business with his father-in-law in Chicago.
