Walter Henry Halas (January 15, 1892 – December 20, 1959) was an American baseball player and coach of American football, basketball, and baseball. He played college baseball at the University of Illinois at Urbana–Champaign from 1914 to 1916 as a pitcher for the Fighting Illini.[1] Halas later pitched in minor league baseball for the Davenport Blue Sox, Moline Plowboys, and Rock Island Islanders of the Illinois–Indiana–Iowa League. In 1924, he pitched a no-hitter for the Hanover Raiders of the Blue Ridge League.
