Croatian Mate Pavic and Austrian Oliver Marach have won the ASB Classic men's doubles title, emerging from a tiebreak against Belarusian Max Mirnyi and Austrian Philipp Oswald to triumph 6-4 5-7 (10-7).
Top-seeded for this year's doubles action, Pavic and Marach seized the initiative in Saturday's match by breaking early in the first set and winning 6-4.
Yet Mirnyi and Oswald, who knocked out Kiwi Michael Venus and partner Raven Klaasen in Friday's semi-final, fought back to break twice and win the second.
In the tiebreak, it was neck and neck.
The two pairings kept pace with one another until Pavic and Marach earned a 7-5 lead and rode it out to victory, requiring three match points.
"It was a very tough match today, they played very well - in the champion tiebreak, it goes either way, it's like a casino," Marach said.
Both players have won the Classic doubles title before - Pavic with Venus in 2016, and Marach with compatriot Alexander Peya back in 2012.
They're likely to remain together for the Australian Open, having also won last week's Qatar Open final against Jamie Murray and Bruno Soares.
"Yeah we're undefeated in 2018, having a phenomenal start to the year, and we're very happy with that and playing well," Pavic said.
