At the end of every summer, nearly 1 million fans flock to Flushing Meadows for one of the greatest tennis events in the world. As the finale of the Grand Slam, more rides on the US Open than a typical tournament, while its homecourt status in New York City adds that extra bit of electricity to what's already the tennis event of the year. For a little background, here are some of the most pivotal, groundbreaking, thrilling moments in US Open history.
