Us Open 2018  

USTA spokesman Chris Widmaier said Lahyani had gone 'beyond our protocol,' but would be allowed to continue to work matches during the US Open because of his 'exemplary track record as an international tennis official'

'For me, I don't feel sad because I wouldn't even know what I'm expected to feel,' Osaka said after the US Open final.

Novak Djokovic clinched his third US Open title on Sunday beating Juan Martin del Potro.

A few games later, Williams received another warning, this time for smashing her racquet, and that second violation cost her a point, leading to more arguing. Eventually, Willams called Ramos “a thief,” drawing a third violation — and costing her a game

Though her nerves on the tennis court don’t show it, it was a reminder of just how youthful the 20-year-old Osaka is. Not since Maria Sharapova was 19 in 2006 has the US Open had a younger women’s champion

On Saturday, Serena Williams will face No. 20 seed Naomi Osaka, a 20-year-old who is the first Japanese woman to reach a Grand Slam final

Novak Djokovic moved a step closer to a third championship at Flushing Meadows and 14th Grand Slam title overall by eliminating John Millman 6-3, 6-4, 6-4 to get to the tournament's semi-finals for an 11th appearance in a row. He sat out last year because of an injured right elbow

Serena Williams put aside some early shakiness and an early deficit, turning things around with an eight-game run en route to a 6-4, 6-3 victory over No 8 seed Karolina Pliskova for a spot in the semifinals

In the fifth set, Rafael Nadal held three break points at five all, love-40, but Dominic Thiem took the next five points to hold serve. That, Nadal would say afterward, managed to 'break my heart. But I just keep going'

John Millman was adamant he would not be intimidated by Roger Federer, and perhaps was helped by having spent time practicing together a few months ago ahead of the grass-court portion of this season

Serena Williams finished with 18 aces and 47 total winners. A couple of loose points gifted Kanepi a break in the first game of the second set, however, and she couldn't get back on terms

Some quick thinking from Swiss master Roger Federer helped him return Nick Kyrgios' blistering shots

Five-time US Open winner Federer beat Frenchman Benoit Paire to set up a third round clash against Nick Kyrgios. 

Stan Wawrinka survived a scare to reach the third round of the US Open while Andy Murray lost to Fernando Verdasco
