Gallery: The story from an absorbing day four at the 2018 US Open
We look at the action from day four at the US Open at Flushing Meadows.
Angelique Kerber had to dig very deep to get in to the next round.
And so did Petra Kvitova.
Meanwhile, Roger Federer was quietly doing Roger Federer things in Arthur Ashe Stadium.
But spare a thought for Benoit Paire, who just couldn’t get close to the Swiss legend.
Frances Tiafoe was putting every drop he had into his match.
And so was Gael Monfils, although injury would end his chances – again.
Novak Djokovic was producing some magic in the evening session.
With the doubles providing their usual brand of under-valued brand of lunacy.
And the scenery was stunning as ever as the sun set on another brilliant day of tennis.
Second seed Caroline Wozniacki was dumped out in the second round.
Former champion Maria Sharapova felt the heat, but she is stayed alive.
