2011 US Open Series

In tennis, the eighth edition of the US Open Series (known as Olympus US Open Series for sponsorships reasons), includes ten hard court tournaments that start on July 18, 2011 in Atlanta and will end in Winston-Salem for the men and in New Haven for the women on August 28, 2011. This edition has scheduled five separate men's tournaments, four women's tournaments, and the Western & Southern Open that will host both a men's and women's event. The series includes 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 has 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. 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.

The standings below include all players who have received points from at least two tournaments in the US Open Series.

Defending champion, Mardy Fish, last year's finalist, John Isner, and 2010 semifinalist, Kevin Anderson, headlined the event. Isner was nearly the first big upset of the tournament, needing nearly three hours to defeat fellow American James Blake in the second round. Nineteen-year-old Ryan Harrison reached his first ATP Tour semifinal, but ultimately fell to Fish who defeated Isner in a rematch of last year's final.
