A Serena Williams statement put out by the USTA on Sunday night:

“For us, one of our biggest challenges is to let people know that wheelchair tennis isn’t just a neat inspirational activity. It is a professional sport,” he says. “We have 150 pro tournaments throughout the year.”

“Everything,” Del Potro said when asked why he liked the US Open so much. “The stadium, the crowds, the people, the city, everything. It’s so lovely.”

Djokovic beat Federer earlier this year on hardcourt at Miami and on clay at Rome.

“She’s such a strong player. She doesn’t give you anything for free,” Oudin said. “She plays incredible defense. Makes me hit a thousand balls and really is a really great player. I mean, I don’t know what else I could have done. I could have been more consistent and been more patient, but she really made me think out there and made me have to hit a winner on her to win the point.”

You need to write a story about the fact that the women’s game is in such disarray that Melanie Oudin, a 17-year-old kid, is able to beat just about everyone she faces — without any dominant strokes — by simply not collapsing and allowing every other ranked female to self-destruct as they struggle to battle their emotional demons.

“I plan on playing just now,” Murray said. “See what I, you know, do from here. You know, go and obviously take a few days off. You know, been over in the States now, you know, a good sort of six and a half, seven weeks. You know, so I will go home and rest and, you know, make sure I do all the right things and, you know, hopefully be okay.”

Looking to join the two in the semifinals in Wednesday play will be an all-unseeded meeting with Belgian Yanina Wickmayer vs. the Ukraine’s Kateryna Bondarenko, and in the much-anticipated first night match at 7 p.m. EST, new American sweetheart Melanie Oudin vs. No. 9-seeded Dane Caroline Wozniacki.

Andy Murray has the tools to win a Grand Slam event, but he does face a tough question: “Should I stick with a generally effective strategy of counterpunching or change strategies by developing and using bigger shots?” Internal doubts arising from this quandary might be worse than just selecting one option and committing to it.

This is the first time in 128 years of the US Open or U.S. National Championships as it used to be called that no American reached the quarterfinals.
