It was the opening sports event at the new Busch Memorial Stadium - a memorable night in St. Louis history. The largest crowd ever to assemble at a baseball game in Missouri, 47,000 persons, watched the Cardinals defeat the Atlanta Braves, 4-3. The game was played on May 12, 1966, in unseasonably cold weather, and it lasted 12 innings. The end came when pinch-hitting outfielder Lou Brock singled in the winning run. The hard-won victory was both a christening and a climax to a five-year effort to build a downtown sports stadium. Construction was completed in less than two years at a cost of $24,000,000 in private capital. Architects were Sverdrup & Parcel and Associates and Schwarz & Van Hoefen. The design collaborator, Edward Durrell Stone, was chiefly responsible for the distinctive exterior. In the photo, the stadium's twin moveable grandstands appear as diagonal risers along the baselines. Each of these sections will be shifted on hidden rails for the viewing of football games. Capacity seating for baseball games is 50,000; for football it will be 55,000. photo by James Rackwitz/St. Louis Post-Dispatch.
