- Petra Kvitova successfully defended her Connecticut Open title, beating Lucie Safarova, 6-7(6), 6-2, 6-2, to win New Haven for a third time. It was a great week for Kvitova confidence-wise, having come into the tournament with no wins during the summer hard courts and walking away with victories over Madison Keys, Agnieszka Radwanska, Caroline Wozniacki, and Safarova. The win moved her back up to No.4 in the rankings and No.6 in the Road To Singapore.

- Karolina Pliskova was crowned the winner of the Emirates Airline US Open Series. Pliskova played all four weeks of the North American summer, making the final in Stanford and quarterfinal in New Haven. By virtue of playing three or more events, her point total was doubled, giving her a five point edge over Serena Williams. Simona Halep came in third. All three women are in the running for bonus prize money at the US Open.

- From espnW: A hefty profile on CoCo Vandeweghe.

- Vandeweghe tends to spill her own blood. "She's her own worst critic," says Kardon, who started working with her this past May. Jan-Michael Gambill, her coach from 2011-13, tells stories of Vandeweghe's demolishing rackets and leaving handprints on her thighs from slapping herself so hard. "One unforced error would outweigh six winners, then snowball into a lost set"

"Why do I put so much pressure on myself?" Vandeweghe asks. "I don't know. I want to achieve my dreams. I want to be great at what I do."

- From espnW: On Sam Stosur, the last player to beat Serena Williams in a Slam final.

"It's kind of funny," said Stosur, who is seeded 22nd this year, is on the opposite half of the draw from Williams and plays Timea Babos in the opening round. "She's obviously been extremely dominant, particularly over these past 12 months. It's a good feeling. I know I'm capable of matching up with her.

"I'll take it."
