Full draw and schedule available at Apia International website.
Fresh from her Saturday defeat to Victoria Azarenka in the final of the Brisbane International, Kerber faced a tough opening round in Sydney against world No. 20 Elina Svitolina.
The Ukrainian got off to a terrific start as she won the first set, but Kerber was able to show her superiority in the second as she won 6-0 thanks to some terrific serving. Having claimed the momentum, the German made it count in the decider, and she saw out a tough victory in just under two hours.
Her fellow German, Lisicki, had a much easier time of it against Polona Hercog, the 2013 Wimbledon finalist claiming five breaks in the match to prevail 6-4, 6-3.
Surprisingly, it was a similar story for Errani against Suarez Navarro, although it took a huge effort and eight match points for the Italian to complete her two-set victory, per tennis writer Nick Leone:
Australian Stosur fought out one of the matches of the day with Roberta Vinci as she won in a two-and-a-half-hour thriller.
Having lost the opener 6-4, Stosur claimed a key late break in the second to level things and force a decider. She looked to be easing to victory as she went 5-2 clear, only for her Italian opponent to draw level once more.
However, the 31-year-old was resolute and broke again late to pull off an impressive victory, to the delight of the Ken Rosewall Arena crowd, per Apia International:
There was also a home triumph in the men's first round as Jordan Thompson went through against Martin Klizan—who retired at a set and 4-0 down—to set up a second-round clash with compatriot and top seed Bernard Tomic.
There was no such joy for Millman, who was downed in straight sets by Robredo, losing a first-set tiebreak before the Spaniard finished the job with a clinical second-set performance.
America's Alexander Sarkissian—currently No. 195 in the ATP rankings—claimed an impressive victory over Simone Bolelli.
Sarkissian came out the traps fast, sealing two breaks of serve to take the opener. Italy's Bolelli came into the match in the second, but neither player could force a significant advantage, and the Californian eventually claimed the victory in a tiebreak.
Fifth seed Seppi had a better day than his compatriot as he saw off the challenge of Istomin in three sets to set up a second-round match against either Nicolas Mahut or Adrian Mannarino, who play out their all-French affair on Tuesday.
