Spot the top seeds
-- For the first time in Wimbledon history, no woman from the top 10 seeds reached the quarter-finals.
-- Jelena Ostapenko is the last remaining of the 10 junior Wimbledon champions who began the tournament. Only four girls' title-winners have ever gone on to win the women's singles: Ann Haydon-Jones, Karen Susman, Martina Hingis and Amelie Mauresmo.
- Who's saying what -
"He's two metres tall. He's serving from the sky. He's serving a lot of aces. I'm able to return when I can reach the ball, but it's very often that I'm not reaching the ball."
-- Gilles Simon on facing Juan Martin del Potro.
"Yeah, of course. I lose."
-- Daria Kasatkina, when asked if there was anything about her match against Angelique Kerber that she didn't like.
"I did ballroom dancing from five to 12. I quit for some years, but now I'm doing it as a hobby. I think it helps a lot because you have to be very coordinated to do it, and also those small steps, which are very useful in tennis."
-- Jelena Ostapenko, who said samba was her best dance.
"I don't know."
-- Juan Martin del Potro on how he can beat Rafael Nadal in the quarter-finals.
"I think she said, I'm sorry. I'm like, 'You don't have to be sorry. I'm really happy for you. You really deserved this'."
-- Kiki Bertens on what Julia Goerges said after claiming victory in their quarter-final.
"I hate losing. I mean, that's no secret. But you got to lose. I feel like every time I lose, I get better."
-- Serena Williams.
