Some big names were knocked out of the Australian Open on day four. Here are five matches that caused some of the biggest shockwaves and the best entertainment on a very hot Thursday.
Bernarda Pera bt. Johanna Konta (6-4 7-5)
Unseeded American Pera broke British hearts after knocking out ninth seed Konta in straight sets.
The 26-year-old Brit struggled to find any rhythm in the Melbourne heat and Pera’s aggressive nature made it difficult for her to hit any winners.
The world number 123 made light work of Konta’s usually reliant serving and broke serve four times before sealing the most magnificent victory of her career with a fifth match point.
Defeat was Konta’s eighth in 11 matches, leaving her and new coach Michael Joyce with plenty to work on ahead of the clay season.
Pera initially lost in the qualifying rounds and is only in the main draw as a lucky loser, but this win will surely see her rankings rise well above the top 100.
Novak Djokovic bt. Gael Monfis (4-6 6-3 6-1 6-3)
Temperatures reached 40 degrees on Rod Laver Arena as 14th seed Djokovic came from a set down to beat Frenchman Monfis.
Both players complained about the heat after the match, which lasted two hours and 45 minutes.
Djokovic struggled in the opening set, with four double faults in his opening two service games.
Monfis, who is yet to beat Djokovic in a professional match, then struggled with conditions and had to leave with a doctor after losing the second set.
The Serbian took full advantage of his opponent’s weariness and eased to victory.
Tennys Sandgren bt. Stan Wawrinka (6-2 6-1 6-4)
Former Australian Open champion Wawrinka lost in straight sets to American Sandgren in just his second match back since knee surgery.
The Swiss never looked comfortable on court. The ninth seed was constantly flexing his knee joint, and lost in 88 minutes to the impressive Sandgren.
The world number 93 had never won a Grand Slam match prior to this year’s Australian Open, but now has two back-to-back.
Hsieh Su-wei bt. Garbine Muguruza (7-6 6-4)
Third seed Murguruza also bowed out after suffering a straight sets defeat to Taiwanese Su-wei.
The current Wimbledon champion was another victim of the heat and also need treatment on her foot during the first set.
The Spaniard hit 21 unforced errors against Su-wei, as she now prepares to try and win a second French Open title.
Dominic Thiem bt. Denis Kudla (6-7 3-6 6-2 6-2 6-3)
Austrian Thiem fought back from the brink to defeat American Kudla in a five-set thriller.
The number five seed conceded the first two sets after Kudla produced some masterful tennis, but showed his pedigree in the final three sets to advance.
The 24-year-old has never been past the fourth round at Melbourne Park, but is consider an outside bet to break his Grand Slam duck in Australia.
