SYDNEY, Australia – Samantha Stosur held her nerve in a tense finale to edge out Roberta Vinci and reach the second round of the Apia International Sydney.

Each January, the question on the lips of everyone involved with Australian tennis is: which Stosur will turn up? The confident, baseline-hogging, Grand Slam winning version, or the nervy, error-strewn one struggling underneath the weight of home expectation.

And as Vinci clawed her way back into the third set, a familiar story looked to be unfolding in front of the Ken Rosewall Arena faithful. But having frittered away a 5-2 lead, a relieved Stosur finally dragged herself over the finishing line when the Italian sent a backhand drifting into the tramlines.

In the off-season, Stosur swapped the gym for a more cardiovascular approach, a decision that paid dividends during a 4-6, 7-5, 7-5 victory, which lasted over two and a half hours under the Sydney sun.

“It was a very long match, a very tough match,” Stosur said. “She knows what she’s doing out there, so you’ve got to know how to combat that. I did that at times, not at others, but I’m glad to get through.”

Since reaching the final over a decade ago, Stosur has failed to make it beyond the second round in Sydney. Blocking her path this time is another of the game’s more experienced heads, Daniela Hantuchova.

“If I could get through that and be in the quarters obviously I would be really pleased and really happy, it’s always nice to progress one round further than you’ve been able to for a long time,” Stosur added.

“That would be a really good confidence boost going into the Aussie Open. If I am in the quarters here, then I’ll try to keep going here as long as possible.”

Elsewhere in the bottom half of the draw, there were wins for Belinda Bencic, Ekaterina Makarova and Monica Puig.

Bencic, who made an early exit last week in Brisbane, got her Australian Open preparations back on track with a 7-6(6), 1-6, 6-4 win over Mirjana Lucic-Baroni. Puig was also made to work hard, eventually seeing off Magdalena Rybarikova, 6-2, 3-6, 6-4, while Makarova kept her time on court to a minimum, swatting aside Lucie Hradecka, 6-2, 6-1, in under an hour.
