Palmerbet Sports Team’s Best of the Day preview serves up Australian Open tips for a fascinating semi-final duel between Petra Kvitova and Danielle Collins.

History: Played 1: Kvitova 1 d Collins 0

Last Meeting: Brisbane International, 2019 (R32): Kvitova d Collins 6-7 7-6 6-3

Final Thoughts: It’s a semi-final few could have predicted pre-tournament – or even midway through the Australian Open. But Petra Kvitova’s showdown with Danielle Collins holds plenty of intrigue, with compelling storylines surrounding both players.

After winning the Sydney International, Kvitova’s form has been simply spellbinding. She has won all five matches at the Australian Open in straight sets, losing five games or less in each.

Her biggest test was set to come from home hope Ash Barty in the quarters, but the world No.6’s aggression and precision blitzed the Aussie 6-1 6-4. This is her first grand slam semi since winning her second Wimbledon crown in 2014 and her first Australian Open semi since 2012.

Never has the 28-year-old looked so determined and focused on the court.

It’s been a stunning revival since a knife attack forced Kvitova to miss the 2017 Australian Open and threatened her career.

But Collins’ remarkable journey to the semis arguably outranks even Kvitova’s. The 25-year-old American had never even won a grand slam match prior to this tournament, yet the world No.35 has played with the confidence of a seasoned major winner.

She annihilated world No.2 Angelique Kerber 6-0 6-2 in the fourth round, then counterpunched brilliantly to oust Anastasia Pavlyuchenkova 2-6 7-5 6-1 in the quarters.

The pair met on New Year’s Day in the Brisbane International, where Collins gave more than a hint of her fighting qualities.

Kvitova came from a set down to claim a hard-fought win that took over three hours.

Kvitova is impossible to back against in her current mood. But Collins is set to give the Czech her first genuine test of the tournament.
