"(Ernie) Mehl worked nearly 50 years for The Star, serving as sports editor from 1950 to 1965. Over that time, Mehl relentlessly beat the civic drum in an effort to bring a major-league baseball team to Kansas City. In 1955, his dream came true when the Kansas City Athletics came from Philadelphia. When they moved to Oakland in 1967, Mehl was at the forefront of the effort to persuade the American League to grant an expansion franchise to Kansas City and to persuade Ewing Kauffman to buy it."
