Photos from Flushing Meadows: Day 7

​Each day during the U.S. Open, we'll feature Anita Aguilar's photography, captioned by Steve Tignor. For more photo galleries, click here.

David Ferrer was stretched to the limit, and beyond, in his four-set loss to Gilles Simon.

Few of us had ever seen Ferru so exhausted.

Which is the rarer feat, winning the U.S. Open or wearing down David Ferrer? I’m thinking the latter. Simon pulled it off yesterday.

And then accepted Ferrer’s congratulations.

Maria Sharapova looking long.

Unfortunately, that’s where a lot of her shots landed against Caroline Wozniacki.

Wozniacki kept her hair away from her racquet...

...and her shots close to the corners.

The fired-up former No. 1 beat Sharapova for the first time in three years, in what she said was one of the biggest wins of her career.

“Sweet Caroline”s performance made the crowd’s day at the Open.

Dad’s, too.

After the rain, came the Bird.

Tomas Berdych has left his summer slump behind and advanced to the fourth round.

Marcel Granollers, and his racquet, had Roger Federer in their sights for a set.

But by the end Federer was hearing the applause...

...and his box was all smiles.

Dominic Thiem and the U.S. Open are getting along nicely; he moved into the fourth round in his first main-draw appearance at Flushing Meadows.

As for Richard Gasquet, he was drenched in sweat and looking exhausted against his countryman Gael Monfils.

Gasquet lost in straights, but not before giving the fans in Armstrong a look at his backhand in full flight.

Monfils has, strangely enough, won all nine sets he’s played, without incident. But he says everything is OK: “I’m cool,” he said. “As usual.”

Belinda Bencic, 17, won the first of what we assume will be many matches in Arthur Ashe Stadium.

Afterward, she called the court “mega cool” in English, and “wunderbar” in Swiss German. It could be the beginning of a long and fruitful relationship.
