Who's saying what
"It's kind of nice sometimes, when it's hot, to be standing in the shade. I'm like, oh, it's probably 15 degrees cooler here than it is on the other side, so I'll just let her run a little bit more."
- Caroline Wozniacki on an extra tactic when temperatures are in the low 30s.
"I really enjoy baking, which is tough on the road. Yeah, so whenever I'm home I feel like I'm constantly in the kitchen."
- Madison Keys on what she does to relax.
"lol..popped a calf muscle running downstairs to interview Novak on-court after Mikhail withdrew Getting old sucks."
- Darren Cahill, former player and now coach of Simona Halep and ESPN analyst, on Twitter.
Sock on the fence
- Jack Sock celebrated his shock win over 2014 champion Marin Cilic by breaking into an imitation of a swordsman. It was in honour of his friend and US Olympic fencer Miles Chamley-Watson who was watching from the sidelines.
Watch it, Rafa!
- Spanish star Rafael Nadal will never have an excuse for being late on court as he wears a wristwatch reported to be worth $775,000. According to Forbes magazine, Nadal sports a RM 27-02 Tourbillon watch every time he plays a match.
Vinci, the Italian American Olympian
- Last year's runner-up Roberta Vinci of Italy walked into her post-match news conference after making the fourth round wearing a United States Olympic sweatshirt. "I got it last week in New Haven. You like it?" she asked.
