A few sighs of relief for women's world number one Iga Swiatek after her second round match at tennis' Australian Open

The top seed from Poland has advanced with a tense three-set win over American Danielle Collins.

Swiatek describes her mindset when she trailed 4-1 in the deciding set - on Sky Sport.



Meanwhile leading men's names Casper Ruud and Alexander Zverev have also survived marathon matches - both needing fifth-set tiebreaks to advance.

Ruud snuck past Australian Max Purcell, while Zverev fought off a superb display from Slovakian qualifier Lukas Klein.
