The U.S. Open is into the homestretch. The women's quarterfinals are set after Victoria Azarenka rallied to beat Ana Ivanovic 4-6, 6-3, 6-4 on Tuesday in a match that was pushed back from Monday because of a rain delay. Meanwhile, Novak Djokovic and Andy Murray are looking to secure their spots in the quarterfinals later in the day.
It's been an eventful week since we last visited the photo wire. Roger Federer admitted that he "self-destructed" in his fourth-round loss to Tommy Robredo; rain and humidity wreaked havoc; Serena Williams solved Sloane Stephens; five over-30 men made the fourth round, the most since 1982; and four women who are either unseeded or seeded outside the top 15 advanced to the quarterfinals. Through it all, the title favorites remain, meaning that the rest of the second week should be a doozy.
Here are some of our favorite pictures from the last week at the U.S. Open.

Li Na: Focused and fired up, Li hadn't dropped a set entering the quarterfinals. (Emmanuel Dunand/AFP/Getty Images)
Roger Federer: The 17-time Grand Slam champion committed 43 unforced errors against Robredo in his first straight-set loss at the U.S. Open since 2002. (Timothy Clary/AFP/Getty Images)
Bob and Mike Bryan: Asked about the evolution of their famous chest-bump, the Bryans admitted they didn't always nail the execution. Mike said Bob broke his sternum one time. "I don't know if I broke his sternum," Bob said. "Bruised it. He was struggling breathing for a couple days. All these photo shoots and commercials where we are doing 50 to 100 [bumps], we have really honed our skill." (Matthew Stockman/Getty Images)
Carla Suarez Navarro: The 18th-seeded Suarez Navarro is into her third Slam quarterfinal. This is the 25-year-old Spaniard's best run at the U.S. Open in six appearances. (Stan Honda/AFP/Getty Images)
Victoria Azarenka: The No. 2 has needed all the help she could get to survive her last two matches, edging Alize Cornet and Ivanovic in three sets. She's winning ugly, which is to say, she's winning. (Don Emmert/AFP/Getty Images)
Rafael Nadal: If you thought this perspiration was bad from Nadal's third-round win over Ivan Dodig ... ball kids had to wipe down the court during changeovers in Nadal's fourth-round win over Philipp Kohlschreiber on a very humid Monday in New York. All of the players who played on Labor Day looked like they had just stepped out of the shower. (Stan Honda/AFP/Getty Images)
Serena Williams: She twisted, she twirled and she even threw in a squat. Serena's win over Stephens was exactly what she needed. (Clive Brunskill/Getty Images)
Ivan Dodig: A flying backhand volley seems like a risky gambit, but you have to pull out all the stops when you're trying to beat Nadal. (Clive Brunskill/Getty Images)
Sloane Stephens: Despite her fourth-round loss to Williams, Stephens hung in right alongside the world No. 1 in the first set. Lots to build on and a good confidence builder for the rest of the season as the 20-year-old shoots to break into the top 10. (Don Emmert/AFP/Getty Images)
Roger Federer: Federer was surprisingly resigned in his post-loss interview, admitting that he's struggled over the last three months and simply didn't have it against Robredo. Does he still have it in him to win seven best-of-five matches over two weeks? Let the debate continue. (Clive Brunskill/Getty Images)
