De Minaur, Kvitova top in Sydney

It was a gutsy performance from the two-time Wimbledon champion who only finished her semi-final against Aliaksandra Sasnovich in the early hours of Saturday.

Barty is Australia's highest ranked player in the world at 15 on the WTA rankings and she again illustrated the growing maturity that has helped propelled her to the cusp of the top 10.

This week Alex didn't drop a single set, and he impressed on Saturday when he won the semifinal against Gilles Simon in the morning (6-3 6-2) before beating in the evening Andreas Seppi in the final 7-5 7-6 (5). "I'm really happy", de Minaur said.

The talented young Australian player claimed the feat after losing two ATP finals a year ago: the Sydney, and Washington opens, in addition to the 2018 Next Generation ATP Finals in the Italian city of Milan.

De Minaur explained he asked organizers to push his match to Tuesday (in that case, he or Pedro would have had to play in back-to-back days) but that was a lost battle once they released their Monday program, saying they have been punishing the home players in some way for competing at home tournaments before the Open.

He also showed no sign of nerves, getting 73 per cent of his first serves in and bouncing back immediately after being broken midway through the second set and then three times when the world No.37 had mini breaks in the tiebreaker.

Alex De Minaur celebrates.

"I knew coming in that if I wanted to come away with a trophy, I was going to have to play two really tough matches", he said.

The Italian earned his first break point of the set before capitalising on a De Minaur double-fault to lead 4-3.

His reward is a return on Wednesday to play Mirza Basic or Henri Laaksonen for a likely third-round shootout with the great Rafael Nadal.

Sharma prevailed against countrywoman Priscilla Ho 7-5, 4-6, 6-1 in an enthralling contest on the outside courts lasting two hours and nine minutes.

"I came out and absolutely wouldn't be the player I am today if I didn't go".

"I wasn't doing too well in the pro circuit and ended up going to Vandy and definitely the coaches there took me under their wing and developed me for a good four, five years", Sharma said.
