Defending champion, Mardy Fish, last year's finalist, John Isner, and 2010 semifinalist, Kevin Anderson, headlined the event.

Defending champion, Victoria Azarenka, last year's finalist, Maria Sharapova, and 13-time Grand Slam champion, Serena Williams, headlined the event. Playing her first tournament on American soil since 2009, Williams showed excellent form, serving bagels in her opening round match, and followed that win by upsetting Sharapova in the quarterfinals. With Azarenka's exit in the second round, Marion Bartoli took advantage of the open draw and advanced to the final. In only her third tournament of the year, Williams defeated Bartoli to take the title.

Gaël Monfils and defending champion, David Nalbandian, headlined the event. Atlanta champion, Mardy Fish, who also reached the final of the Farmers Classic, was forced to withdraw from the tournament, citing a bruised right heel. Serbian duo, Viktor Troicki and Janko Tipsarević, who were expected to reach the quarterfinals because of their seedings, joined the lower-ranked American duo, John Isner and Donald Young, in the final eight. Radek Štěpánek took advantage of Fish's withdrawal from the tournament and advanced to the final, where he took out top seed Monfils for his fifth title of his career.

Sloane Stephens' upset over Julia Görges resulted in the American wildcard being the only unseeded player in the final eight, while Ivanovic's upset over Peng Shuai spoiled a semifinal lineup of the top four seeds. Despite sustaining a shoulder injury earlier in the tournament, Agnieszka Radwańska was able to reach the final for the second consecutive year and defeat top-seed, Zvonareva, for the title.

The top 20, including Caroline Wozniacki, Kim Clijsters, and Maria Sharapova, along with Stanford champion, Serena Williams, headlined the event. Despite a long lay-off due to a foot injury, Clijsters was once again forced to retire from her opening round match citing an abdominal injury. The tournament suffered the loss of another headliner early on as defending champion, Wozniacki, was knocked out in the second round. The third round brought about more upsets, as the number three seed, Vera Zvonareva, and Sharapova lost to Agnieszka Radwańska and Galina Voskoboeva, respectively. Despite losing only six games en route to the semifinals, fourth seed, Victoria Azarenka, lost in straight sets to Stanford champion, Williams, who extended her win streak to ten matches. Williams won her second tournament of the Series, defeating Samantha Stosur in the final.

Montreal champion, Novak Djokovic, Rafael Nadal, defending champion, Roger Federer, and Atlanta champion, Mardy Fish, headlined the event. The top eight seeds cruised to the quarterfinals with exception to fifth-seeded, David Ferrer, who lost his third round match to Gilles Simon. The quarterfinals brought a pair of upsets as former world number ones, Rafael Nadal and Roger Federer, bowed out to Fish and Tomáš Berdych, respectively. Neither player could follow up the win, and instead, Andy Murray handed Djokovic his second loss of the year after the world number one was forced to retire from the championship match.
