"Mule" Haas was a member of Connie Mack's great pennant-winning teams of 1929, 1930. and 1931. He formed the dangerous, well-balanced outfield for the A's with "Al" Sim- mons and "Bing" Miller. Haas was not a great player but he was aggressive and colorful. He could hit a ball as hard and as far as anyone. He covered a lot of territory in the Athletic outfield, too. Haas played with the A's from 1928 through 1932, was traded to the Chicago White Sox in 1933, and returned to the A's as a free agent in 1938. His value to a ball club is well indicated by the fact that he led the major leagues in sacrifice hits for six years. Haas was appointed a White Sox coach this year.
