In tennis, the sixth edition of the US Open Series (known as Olympus US Open Series for sponsorship reasons), included ten hard court tournaments started on July 20 in Indianapolis and ended in New Haven, Connecticut on August 29.^[1] This edition has scheduled five separate men's tournaments, four women's tournaments, and the Pilot Pen Tennis Tournament hosted both a men's and women's event. The series included two ATP World Tour Masters 1000 and two WTA Premier 5 events to headline the series.

To be included in the standings and subsequently the bonus prize money, a player had to have countable results from two different tournaments. Players finishing in the top three in the series can earn up to $1 million in extra prize money at the US Open.^[2] Roger Federer received the largest US Open pay day of $2.4 million in 2007 after capturing the title in both the US Open Series and the US Open championship.
