Aus Open Diary: My brother still makes fun of me, says Zverev

'My brother still makes fun of me. My mom is still there. Dad is still there. My dog doesn't even realise who I am'

Alexander Zverev can no longer hope to fly under the Grand Slam radar following a brilliant 2017 season but the hype has done little to change things on the home front, the 20-year-old wunderkind insists.

His 30-year-old brother Mischa's recent marriage has meant different living arrangements in Monaco but that has done little to loosen the bonds of one of the world's tightest-knit tennis families.

World number 35 Mischa still finds time to tease 'Sascha', despite his little brother's rapid ascent up the rankings.

"We obviously have separate apartments. He has a wife now, and, you know, I'm a little bit by my own," fourth seed Zverev told reporters after reaching the Australian Open second round on Tuesday with a 6-1, 7-6(5), 7-5 win over Thomas Fabbiano.

"But, you know, still we travel a lot as a family, because my dad is obviously my coach still. My mom travels with him," he added. "(On court) they asked me what changed for you since you're 20, number four in the world."

"At home, nothing changed. My brother still makes fun of me. My mom is still there. Dad is still there. My dog doesn't even realise who I am, so, you know, nothing changes at home."

His dog, a toy poodle, may be oblivious to his owner's renown but few at Melbourne Park remain ignorant of the 6ft-6in tyro, who has been touted one of the young players most likely to upset the old cartel of Roger Federer and Rafael Nadal.

Zverev announced himself with a third round appearance at the tournament last year, giving Spanish great Nadal a huge five-set scare before bowing out with general acclaim.

Despite racking up six titles and becoming the youngest player to win a Masters 1000 trophy since Novak Djokovic, Zverev is yet to break through to the quarter-finals of a grand slam, a hole on his tennis CV he is desperate to fill.

He has an impressive support team to help him achieve that, with former world number one Juan Carlos Ferrero coaching along with his father, who played Davis Cup for Russia.

Since a maiden appearance at the season-ending ATP Tour Finals in November, Zverev's preparations for Melbourne Park have been scratchy, with losses to David Goffin and Thanasi Kokkinakis at the Hopman Cup in the lead-up.

But that was quickly forgotten on a sunbathed Rod Laver Arena on Tuesday as he roared through the first set in 24 minutes against 73rd-ranked Italian Fabbiano, looking every inch the young man in a hurry.

From there it all became a bit "sloppy", he said, as his 28-year-old opponent began hammering away like a grand slam heavyweight rather than a man with no titles or wins against top-10 opponents.

Fabbiano served for each of the second and third sets but Zverev rallied and closed out the match with a barrage of clean hitting, setting up a second round clash against fellow German Peter Gojowczyk.

He will carry his family's hopes alone now, with brother Mischa out of the tournament after retiring hurt against Chung Hyeon.

He joked that his mother still woke him up every morning but added seriously that he was becoming "more consistent with age", a concerning development for other players in his draw.

"I think that's also something that is a factor of maturity," he said.

Kerber consigns 2017 to the history books

Angelique Kerber has turned the page on a horror 2017 season and is focused firmly on making a fresh start to her career, the German said after sailing into the second round at Melbourne Park on Tuesday.

The 29-year-old enjoyed a bumper 2016, winning the Australian and US Opens, picking up an Olympic silver medal and becoming the first German number one since Steffi Graf.

Her form, however, deserted her last year when she failed to win back-to-back matches at 13 events and made just one final, at Monterrey, to finish the year at number 22.

"You know, I think last year I will actually not speak about this anymore," she told reporters after defeating fellow German Anna-Lena Friedsam 6-0, 6-4 at the Hisense Arena.

"I mean, last year was really not the best year, everybody knows, and it was a lot of new experience. But I'm also thankful about all the things, because I think I'm growing ..."

Kerber signalled her resurgence with her triumph at the Sydney International on Saturday and was optimistic about 2018 following her flawless start to the new season.

"I think so far it was a good season, the start of the good season, and I'm just trying to playing every single match each."

"I'm not trying to focusing too much on ahead, on past, or what's happened in the last year. I'm just trying to really restart again and try to enjoy my tennis again..."
