New York: US Open headlines and sidelines on Wednesday, the 10th day of the 2016 tournament at Flushing Meadows:
Nishikori stuns Murray in five sets
Serena sees off battling Halep
Murray fumes over 'gong show'
Wawrinka downs tearful Del Potro
Pliskova into first Slam semi-final
Who's saying what
"It would be a living hell."
- Serena Williams when asked what it would be like if she had a twin sister.
"I have not let anyone down. I tried my best."
- Andy Murray after his stunning defeat to Kei Nishikori.
"My concentration went off. But sure they have to stop the point."
- Nishikori on the controversial stoppage in play when the sound system on Arthur Ashe Stadium burst into life when Murray had break point in the fourth set.
"I was more angry before with myself on the court. Sometimes I'm still smashing my racquets — but more in practice than in the matches."
- First-time semi-finalist Karolina Pliskova
"Unfortunately I'm in the part of the draw with Serena, so it would be very tough to get through this one."
- Pliskova plays down her chances of a title in New York.
- On September 7, 1997, Martina Hingis, just 16 years old, beat 17-year-old Venus Williams in the youngest ever Grand Slam final in New York. Both women were still playing at this year's event. Venus exited in the fourth round of the singles despite having a match point against Karolina Pliskova while Hingis featured in women's and mixed doubles.
Pain and glory for Djokovic
- Novak Djokovic has reached the semi-finals by completing just two full matches. He has had one walkover and two shortened matches after opponents retired. It's all familiar for the world number one. In 2011, he received two retirements en route to the US Open title. He also received one retirement and one walkover on his way to the semi-finals at Roland Garros.
Czech it out
- Karolina Pliskova is the first Czech woman to reach the US Open semi-finals since Jana Novotna in 1998, when Pliskova was just six years old.
Beat you to it, brother
- Jamie Murray had bragging rights over brother Andy by making the semi-finals first on Wednesday when he and partner Bruno Soares beat Chris Guccione and Andre Sa in the men's doubles last-eight.
- Ten of the 16 girls to reach the third round of the US Open juniors event are American, the most ever at the tournament since the draw was expanded to 64 in 1984.
5-0 - Nishikori's record over top five players at the US Open
9 - completed sets by Novak Djokovic are the fewest en route to a Grand Slam semi-final in the Open Era.
18/50 - aces and winners hit by Serena Williams in her quarter-final win over Simona Halep.
