Serena Williams, Caroline Wozniacki on course for doubles, singles final in Auckland

Serena Williams and Caroline Wozniacki have booked their place in the doubles final of the ASB Classic in Auckland - and there's still the possibility they could face off in the singles. 

On Friday, Williams and Wozniacki overcame Belgian pair Kirsten Flipkens and Alison van Uytvanck 7-6 (11-9) 6-2 to win their doubles semi-final to book their place in the final. 

They'll face Cori 'Coco' Gauff and Caty McNally or Asia Muhammad and Taylor Townsend in the decider, those pairs playing in the second semi-final on Saturday. 

Before winning their doubles match, Williams and Wozniacki had won their respective quarter-finals singles matches, beating Germany’s Laura Siegemund and Julia Gorges. 

Williams will face Amanda Anisimova for a spot in the singles final, while Wozniacki squares off against Jessica Pegula. 

Williams is excited of the prospect of doing the double in Auckland, having previously done it multiple times with her older sister Venus, most notably at Wimbledon in 2002,09, 12 and 16.  

"I've done it before with my sister so I'm good at this," said Williams. "We're still really close, me and my sister, so I'm sure me and Caroline will still be super close.

"We've still got to win matches, we're not in the final yet." 

Wozniacki, who is retiring after the Australian Open later this month echoed Williams' thoughts. 

"It feels great," Wozniacki said after reaching the doubles final. "It's been so much fun. 

"We started moving our feet really well in the second set and Serena always has my back out there so it was awesome, so much fun. 

"I'm so happy to be here, happy to be playing with Serena, so happy to be through in the singles."

Williams and Wozniacki had never played doubles together prior to this tournament.
