Keys holds to go 4-2 and, with that, Krunic buries her racket into the ground. The Serbian is fighting Keys and her own mind at the moment, beating herself up as the American looks to accelerate away from her. Keys can play a lot better than this, but she’s getting there. Elsewhere, Cilbulkova serves to get things under way against Kerber, the No 4.
Keys leads 3-2 in the final set against Krunic! Over on Armstrong, Kerber, the 2016 champion in New York, and Cibulkova are out warming up. In the men’s draw, Millman is struggling to bat away Mikhail Kukushkin – they’re at 3-3 in the final set.
On court 17, Caroline Garcia and Carla Suárez Navarro are slogging it out. The former took the first set 7-5 but trails in the second 3-2. With Bertens’s match finishing up on Armstrong, that means that Kerber will be on court shortly, against Cibulkova.
So, a classy embrace between Bertens and Vondrousova at the net at the end of that one, but the former will feel she totally blew her chance to edge towards another major. But for the 19-year-old, and world No 103, what a result! And that means one of Vondrousova, Siniakova or Tsurenko will reach the quarter-finals of the US Open.
Vondrousova beats Bertens 7-6, 2-6, 7-6!
Marketa Vondrousova sends Kiki Bertens packing. The Czech teenager comprehensively wins the tie-break 7-1, to knock out the Dutch No 1 who won the Cincinnati Masters earlier this month, and reach the the last 16 of a grand slam for the first time. Over on Arthur Ashe, Keys is 2-1 up in the second.
Bertens was in real trouble, but fights back to 6-6 in the third and final set on Armstrong. As for Keys, she’s well into her stride now after taking the second 6-1. She has just played a smart backhand, leaving Krunic with too much to do from the baseline. And Keys takes the first game too.
Bertens is making a bit of a mess of things on Louis Armstrong, she’s been pegged back once more by Vondrousova after going 4-2 up in third. They’re duelling at 5-5 now, with the teenage Czech having already served to stay in it. Either way, Bertens is making hard work of it. On Arthur Ashe, Keys has romped into a 5-1 lead in the second. The American will serve to take things to a deciding set. In the men’s side of the draw, Millman has just taken the third set 6-1 against a faltering Kukushkin.
Keys has won three straight games, she’s 3-0 up and the second set seems to be drifting away from Krunic, who has the physio out looking at a knee problem after a slip a few moments ago. It’s been heavily bandaged up, a bit cumbersome. In the doubles, Broady and Collins have come up short in straight sets. Jamie Murray and Bruno Soares are just out on court 5. Meanwhile, Millman is 3-1 up against Kukushkin in the third, a set apiece.

Madison Keys bounces back with a bang, to get off to a blistering start to the second start. She leads 2-0 in the second, breaking Krunic to give herself a firm platform to build on. Over on Louis Armstrong, Kiki Bertens is in the driving seat, 4-2 and 15-0 up in the third, serving to edge closer to the game.
Keys loses the first set 4-6! The American survives two set points but cannot escape a third, with Krunic piling a powerful serve straight down the middle of the court. A wonderful opening set for the Serbian. Elsewhere, Bertens is 2-1 up in third, while Millman and Kukushkin are level-pegging.
Krunic ekes out another game, she’s 4-3 up in the first, and her force is proving problematic for Keys, who has made an inconsistent start. Meanwhile, Bertens is back on song, 15-0 up in the third after taking the second. On the grandstand court, John Millman has just lost the second to Mikhail Kukushkin, so they could be in it for the long haul.
Kiki Bertens has seemingly turned things around against Vondrousova, with the former 5-2 up in the second after losing the first. The Czech will serve to prevent Bertens from levelling things up. As for Madison Keys, a power battle is unravelling against Krunic, with the American just fizzing over a 94mph forehand winner. Krunic, though, leads 3-2, with the pair locked at deuce.
Aleksandra Krunic, the Russian-born Serbian who is ranked 49 in the world, has got off to a flyer against Madison Keys. She’s 2-0 up in the first, with a little perfection on serve paving the way so far. It is extremely early days but she the favourite trails in front a home crowd, just as Bertens does in the Louis Armstrong stadium. In the men’s, Millman is behind in the second against the Kazakh.
Vondrousova fights back to win the first set 7-6, winning 7-4 in the tie-break, and that match-up against Bertens is nicely primed for an upset. And Millman cruised to 6-4, but Kukushkin has bounced back from losing the first to go 2-0 up in the second. On Arthur Ashe, Madison Keys, last year’s beaten finalist, trudges out on the court, with the No 14 seed looking very relaxed.

Preamble
Will Madison Keys and Angelique Kerber breeze through? How will Alexander Zverev fare? And might Nick Kyrgios get another little pep talk from the umpire? Some things are more unlikely than others, but it promises to be another bumper day of action, with Kyrgios’s meeting with Roger Federer at the Arthur Ashe stadium the headline event. The Australian has form for causing an upset and beat Federer when they first met at the 2015 Madrid Open. “It’s better to be the underdog than have all the pressure,” a coach-less Kyrgios said. “I’m going to put a lot of expectation on myself to play well. I’m not going to go out there and roll over and be happy to be out there.” As for Federer, the Swiss admits he thinks Kyrgios finds his tricks and flicks irresistible when it boils down to it. “I’m not sure if I’m the guy who’s supposed to pull him to the side. I think he very well knows, deep inside of himself, what he also needs to do.” First up, Kiki Bertens is out on court, duelling with Marketa Vondrousova. The Dutch No 1 is 3-2 up and serving.
