1454 KREJCIKOVA SURVIVES OSTAPENKO SCARE A determined Barbora Krejcikova fought back from a set and a break down to overcome Jelena Ostapenko 2-6 6-4 6-4 in a battle between former French Open champions on Rod Laver Arena.

"Today's match was very tough, I had to dig deep to get this win, so I'm very happy and proud of myself. I'm never going to leave without a fight and I'm happy to show that on the court," Krejcikova said. Krejcikova returned from an eight-minute bathroom break - which she blamed on a broken necklace - and shrugged off a time violation ahead of the decider to secure the victory. Up next for the fourth seed is Victoria Azarenka.

1442 PEGULA OVERCOMES PARRIZAS DIAZ, MEETS SAKKARI NEXT Last year's quarter-finalist Jessica Pegula shook off a slow start to get past Nuria Parrizas Diaz 7-6(3) 6-2 and reach the fourth round, where the American will face fifth seed Maria Sakkari, who beat an ailing Veronika Kudermetova 6-4 6-1.

1221 AZARENKA BRUSHES ASIDE SVITOLINA Two-time Australian Open winner Victoria Azarenka handed number 15 seed Elina Svitolina a comprehensive 6-0 6-2 defeat to advance to the fourth round.

"I feel like I played really well tactically and did not really let her into the game," said the 2012 and 2013 champion. "She's a great defender, she's a great competitor so I had to try to stay on top of her as much as possible and not let her breathe. That was my goal before the match and I feel like I executed that well."
