Nick Kyrgios overcame his inner demons, and a mini foot-fault crisis, to book his place in the third round at Wimbledon.

Kyrgios cast aside Robin Haase 6-3 6-4 7-5 in 96 minutes, the 15th seed having more problems with his entourage than the Dutchman in a second-round mismatch.

“The first two sets, I was pretty impressed with my performance,” Kyrgios said.

“Obviously the third set got a bit rocky. I broke him a couple times, lost my serve, lost focus.

“I knew the match was going to get tough at a certain stage. I’m just glad I got through it and didn’t have to go to four sets.”

As he motored towards victory in the third set, Kyrgios turned on his  courtside box, demanding his supporters –  including his father George – stand up and cheer him home.

“Why are you down? How hard is it to stand up for one game? This could be over in five minutes,” he moaned, over and over.

And despite adding another 19 aces to his massive English summer tally, an agitated Kyrgios also sought an explanation of the foot-fault rule from umpire James Keothavong after repeatedly being pinged for over-stepping the service line.

During a changeover, the official descended from his chair to demonstrate before Kyrgios carried on and eventually completed an otherwise comfortable straight-sets win.

Lightbulb moment! 💡@NickKyrgios just got schooled… by the umpire.

And hey, he handled it with class. #Wimbledon

Gavrilova progresses, Stosur and Tomic out

Daria Gavrilova advanced to the third round at the expense of fellow Australian Samantha Stosur.

Gavrilova’s 6-4 6-1 victory against Stosur edges the 23-year-old to within a win of her long-time goal of reaching the second week at a major other than the Australian Open.

The former top-ranked junior gets another chance on Saturday against unseeded Belarusian Aliaksandra Sasnovich, after she was bundled out in round two of last month’s French Open.

Ash Barty won her tour-topping 10th grass-court match of the season to storm into the third round of Wimbledon with a 6-4 7-5 win against Eugene Bouchard.

Gavrilova’s triumph over Stosur marks her maiden grand slam second-round  outside of Melbourne.

“(But) I’m still trying to get to second weeks,” the world No. 26 said.

“That hasn’t been happening so it’s nice to make that little step forward and make third round of three slams now.

“It feels pretty good, especially with the way I’ve been playing and not having drama matches. It doesn’t happen too often.

Gavrilova is also thrilled to have turned the tables on Stosur with a more aggressive performance after losing her previous two matches to the former US Open champion on clay this season in Prague and Paris.

“I felt like I had to get on the ball early and hurt her before she does,” Gavrilova said.

Her reward is a big opportunity against Sasnovich, who backed up her stunning first-round triumph over pre-tournament title favourite Petra Kvitova with a straight-sets win over rising American Taylor Townsend.

“She’s had a great year. She’s been on a roll and she’s actually been really tricky on the grass,” Gavrilova said.

“She hits the ball super low over the net. She doesn’t hit it flat. It’s just a different ball and I think she has a pretty good effective serve on the grass.

“It’s going to be tricky.”

Meanwhile, Japanese star Kei Nishikori ended the hope of another all-Australian battle in the third round, defeating Bernard Tomic 2-6 6-3 7-6 (9-7) 7-5.

Nishikori, the 24th seed, will face Kyrgios in the third round.

Elsewhere, teenage ace Alex de Minaur was the first Australian through to the last 32 after posting a 6-2 6-7 (8-10) 7-5 6-3 victory over Frenchman Pierre-Hugues Herbert.

And Matt Ebden joined them in the last 32 with a 6-3 7-6 (7-5) 4-6 6-1 win over veteran French qualifier Stephane Robert.
