Nick Kyrgios' heartbreaking reveal after win over Alex de Minaur

Nick Kyrgios has opened up further about his family heartache after beating Alex de Minaur to advance to the quarter-finals at the Canadian Open.

Kyrgios was too good for his compatriot on Thursday, winning 6-2 6-3 for his 15th victory in his last 16 matches.

The only loss Kyrgios has suffered during that stretch was against Novak Djokovic in the Wimbledon final.

De Minaur entered the first-time showdown with his Davis Cup teammate as Australia's No.1 male player, but copped a nasty reality check at the hands of the hottest player on tour.

Kyrgios needed barely an hour to wrap up the victory, which guarantees him another important rankings boost ahead of the US Open starting on August 29.

Speaking in his on-court interview, Kyrgios was happy with the performance but expressed his desire to get home to see his family.

The Aussie star revealed earlier this week that his mother is sick in hospital, while his father is also not in good health. His brother Christos also recently had his first child.

"I am missing home, I'm not going to lie," he said.

"I haven't seen my mum and dad in about three months. I'm missing them but at the same time I know I've only got a couple more tournaments before I go home."

On Wednesday after his stunning victory over World No.1 Daniil Medvedev, Kyrgios wrote a touching message to his mother on a courtside camera lens.

"Be strong Ma," he wrote.

Speaking before Wednesday's match against Medvedev, Kyrgios said: "It's hard to be away from Australia now. My mum is in hospital, my dad hasn't been very well.

"People only see me winning, losing, throwing a racquet. They do not really understand the challenges that we players face in our personal lives."

Nill Kyrgios has been forced to remain in Australia while her son is overseas, missing his extraordinary run to the Wimbledon final.

Speaking before the Wimbledon final, Nill told the Sydney Morning Herald: "My kidneys are reaching very close to the end of their life".

She revealed she's booked in to get a kidney from her husband and hopes it will be compatible.

Nick Kyrgios continues sparkling run of form

At times on Thursday it looked like Kyrgios was toying with de Minaur, who barely won a point in the opening four games.

He finally got on the board but Kyrgios, mixing stylish serve-volley plays with ferocious power from the back, effortlessly took the opening set in 23 minutes before immediately grabbing an early break in the second.

He briefly lost composure after failing to serve out the match at 5-2, but regained his cool to clinch victory with a ruthless fourth break of de Minaur's serve.

"It's never easy playing a friend, particularly if they're Australian. So I just got out here and got the job done," Kyrgios said.

"To play Alex, we're such good friends, and he's having such a good career so far carrying the Australian flag and it was just tough mentally.

"I played the way I had to play. He's a hell of a player. If you play to his strengths, he's one of the best players from the back in the game and he's so fast."

The red-hot Wimbledon runner-up is projected to rise from 37th to No.27 in the standings and could crack the world's top 15 if he backs up last week's success in Washington with an eighth career title on Sunday.

That would secure Kyrgios a crucial top-16 seeding in New York, ensuring the 27-year-old wouldn't play a higher-ranked rival until at least the second week at the season's final grand slam.

Kyrgios' more immediate focus is on Hubert Hurkacz, who he will face for a place in the semi-finals for a sixth tournament running outside of an injury-enforced withdrawal in Mallorca the week before Wimbledon.

Hurkacz beat Kyrgios two months ago on the Halle grass courts and advanced to the last eight on Thursday with a fighting 6-7 (6-8) 6-2 7-6 (7-3) third-round win over Albert Ramos-Vinolas.
