Was a 3 sport star at Cuyahoga Falls High School. He played 3 years with the National A.C. team before joining Speed Bosworth's Akron Yankee Jrs., a team of All-City players. He batted over .400 for the 2 years he played with the Yankee Jrs. In 1937 Dain (playing with the Yankee Jrs.), was voted the Akron District winner of the "Greatest Sandlotter" contest by the Times-Press. A total of 43,694 votes were cast in the contest. In 1938 he signed a pro contract with the St. Louis Cardinals and was assigned to Portsmouth, OH in the Mid- Atlantic League, thereby starting a professional career that would last 17 years. The leagues he played in look like a baseball travelogue. He played in the International, Three I, Texas, Pacific Coast, American Association, Southern and Western International Leagues. And in the National Leagues as a major leaguer, Clay played outfield for both the St. Louis Cardinals and the Cincinnati Reds. An arm injury curtailed his major league career.
