Missing the second part of 2019 due to a wrist injury, Marketa Vondrousova is back in action in Adelaide, reaching the quarter-final following a 6-0, 6-0 triumph over a qualifier Arina Rodionova in 51 minutes. Marketa fended off all five break chances to keep serve intact, storming over the opponent to take 75% of the return points and deliver six breaks from eight opportunities, sealing the deal in no time at all and cruising into the quarter-final.
In a much closer encounter, Belinda Bencic took down Julia Goerges 7-6, 7-6 in an hour and 49 minutes, beating the German for the third time in five meetings. Goerges won one point more than Bencic and had a massive opportunity to grab the opener, leading 5-3 and wasting a set point at 6-5 in the tie break, fighting strong in set number two as well before falling in another tie break.
Serving at 3-5 in the first set, Belinda survived a couple of deuces and broke back in the next game to level the score at 5-5 and extend the set, fending off that set point in the tie break to clinch it 8-6. The Swiss served for the win at 5-4 in set number two, getting broken and wasting another chance of sealing the deal in game 12, trading breaks in those ultimate moments before Bencic won the tie break 7-4 to advance into the quarters.
Danielle Collins stormed over the fellow American Sofia Kenin 6-3, 6-1 in swift 70 minutes, delivering the third victory in three clashes with the younger opponent. Dropping only 12 points in eight service games, Danielle suffered one break and stood all over Kenin on the return, earning five breaks from 11 chances to stay in front all the time.
Collins took the opener with a single break in game eight, staying on the same course in set number two with four more breaks of serve under her belt to move over the finish line in no time at all and stay in contention for the title.
In the battle of two great friends, Donna Vekic prevailed against Maria Sakkari 2-6, 7-5, 6-1 in two hours after winning just four points more. The Greek produced flawless tennis in the opening set to take it 6-2, dominating on her serve and earning breaks in games one and three.
Donna bounced back in set number two, converting the fifth set point in the 12th game and gathering momentum ahead of the decider where she dominated to reach the last eight. Dayana Yastremska led 6-3, 2-0 against Angelique Kerber when the German had to retire due to back problems, putting her Australian Open campaign in doubt just a couple of days before the start of the first Major of the season.
