Rafael Nadal will face Damir Dzumhur in the third round of the 2018 Australia Open after he defeated Leonardo Mayer 6-3, 6-4, 7-6 (4) on Wednesday to move into the next stage of the competition.
Grigor Dimitrov survived an early scare against American Mackenzie McDonald, but the Bulgarian pulled through over five sets to edge his way into the third round 4-6, 6-2, 6-4, 0-6, 8-6.
Marin Cilic also moved on from the second round after beating Portugal's Joao Sousa in straight sets 6-1, 7-5, 6-2, while Gilles Simon was forced to retire in the second set of his clash against Pablo Carreno-Busta, leaving the Spaniard to advance.
Jo-Wilfried Tsonga twice hit back from a set down to come back and beat Denis Shapovalov 3-6, 6-3, 1-6, 7-6 (4), 7-5 in a gruelling five-set war, teeing up a third-round meeting against Nick Kyrgios, who beat Viktor Troicki.
Caroline Wozniacki, Elina Svitolina and Carla Suarez Navarro all progressed in the women's singles, although Anastasia Pavlyuchenkova fell out of the running after a surprise straight-sets defeat to Kateryna Bondarenko.
No. 12 seed Julia Gorges also exited in the second round following a 6-4, 6-3 loss to clinical Alize Cornet, and Marta Kostyuk etched her name in the Australian Open history books with a win over Olivia Rogowska.

Nadal's spot in the Australian Open third round was confirmed with a controlled 6-3, 6-4, 7-6 (4) win over Mayer, clinching an impressive 80 per cent of his first-service points, per AusOpen.com.
Mayer's immediate break-back in the third set was his only time trumping Nadal's serve, and last year's runner-up looked in good shape throughout his clash against his Argentinian opponent, via Eurosport UK:
His third-round foe, Dzumhur, will be the first seeded opponent Nadal encounters in the competition, and the Bosnian demonstrated some promise in his 7-5, 3-6, 6-4, 6-1 victory over Australian native John Millman.
Dimitrov made a slow start against McDonald and suffered a bagel defeat heading into the decisive fifth set of their encounter.
The third seed won, but broadcaster Andrew Scaglione praised the efforts of the losing qualifier:
No. 10 seed Carreno-Busta led Simon before the latter was forced to stop due to injury, and is lined up for a clash with another Gilles, Luxembourg's Muller, following his five-set war against Tunisian Malek Jaziri.
Fifth-seed Cilic showed his Open title credentials beating Sousa 6-1, 7-5, 6-2, and he'll face Ryan Harrison in Round 3 after the American edged 31st seed Pablo Cuevas 6-4, 7-6 (5), 6-4:
Australian star Kyrgios once more showed some wastefulness in his 7-5, 6-4, 7-6 (2) beating of Troicki, and he'll next face Tsonga, who had his back to the wall in a five-set war against Shapovalov.
Britain's Kyle Edmund advanced thanks to a straight-sets win over Denis Istomin, while seeded favourites Diego Scwhartzmann and Andrey Rublev beat Casper Ruud and Marcos Baghdatis, respectively, to progress.
Nikoloz Basilashvili and Andreas Seppi each failed to drop sets in wins over respective second-round opponents Ruben Bemelmans and Yoshihito Nishioka. Ivo Karlovic was pushed far harder against Yuichi Sugita, whom he beat 7-6 (3), 6-7 (3), 7-5, 4-6, 12-10.
Wozniacki looked as though she was heading out of the tournament at 1-5 down in the third set of her meeting with Jana Fett but saved two match points to seal a dramatic 3-6, 6-2, 7-5 result:
Her third-round opponent Kiki Bertens was far more comfortable beating American Nicole Gibbs in straight sets, while Frenchwoman Cornet was similarly confident beating 12th seed Gorges 6-4, 6-3.
That wasn't the only shock of the day, either, as 15-year-old Kostyuk beat Rogowska 6-3, 7-5 to launch her name as a prospect of major potential, holding her own with the world-ranked No. 162:
Seventh seed Jelena Ostapenko advanced after surviving a mid-match wobble to beat Ying-Ying Duan 6-3, 3-6, 6-4, while Svitolina came back from a set down to defeat Katerina Siniakova 4-6, 6-2, 6-1.
Pavlyuchenkova failed to get any foothold of her meeting with Bondarenko and slipped to a disappointing 6-2, 6-3 defeat at Hisense Arena, while Magda Linette shocked No. 22 seed Daria Kasatkina 7-6 (4), 6-2 to set up a third-round matchup with Denisa Allertova.
Magdalena Rybarikova quivered against Kirsten Flipkens and looked to be losing her grip before recovering to win 6-4, 0-6, 6-2, and she'll attempt to limit Bondarenko's underdog run next time out.
