On September 28, 1930, Dizzy Dean impressed in his major league debut by allowing just three hits, and struck out five, during a 3-1 victory over the Pittsburgh Pirates at Sportsman's Park. The 20-year-old product of the Texas League was had joined a club that had sown up the National League Pennant two days before, and the management was getting their first major league look at the kid who would end up immortalized not only in St. Louis. Dean did more than pitch, he also picked up his first major league hit, and scored his first major league run. Dean would win a total of 134 games with the club through 1937. The win that came on that last day of the 1930 season was the first mile marker on a road that would lead to Cooperstown.
