The driver you are referring to is Mike Garcia, who raced midgets simultaneously throughout his professional pitching career. Mike was with the Cleveland Indians from 1948 - 1959, the Chicago White Sox in 1960 and the Washington Senators in 1961.
What we know about the history of the War Memorial is this...
The War Memorial was nothing but an idea on paper in 1952. The original building at that location was a farmers market and trade center for local merchants. The War Memorial as we know it today opened for business in 1955.
The earliest I have been able to confirm racing at the War Memorial is 1964 under the promotion of Jim Vollertson. Jim held midget racing through 1967 according to newspaper articles and history of events conducted there.
I have heard on more than one occasion that midget races were held there in the 50's as well, but I haven't been able to establish a date yet. One of the people who told me this was my father. He and his step father were fans of the wrestling scene both locally and nationally in the 50s, and would have attended the bigger events there. Dad and his step father also attended races at Spencer and Monroe County Fairgounds, so they probably would have attended an indoor show of midgets at the War Memorial too. Unfortunately, Dad passed away almost 2 years ago, so asking for further details isn't possible.
I'll keep digging though.
