Australian Open: Nadal, Williams suffer shock upset in first round

Melbourne: Fifth-seeded Rafael Nadal suffered his first ever 1st-round knock out at Melbourne Park here on Tuesday. Nadal's fellow Spaniard Fernando Verdasco outclassed him in five sets (7-6 (8-6) 4-6 3-6 7-6 (4-7) 6-2) to advance to the second round of this year's first Grand Slam.

Earlier, in women's singles, eighth seed Venus Williams has provided Australian Open fans with the shock of the tournament so far after she was bundled out by World No.47 Johanna Konta of Britain here on Tuesday.

Williams, 35, was enjoying a renaissance of form in the back half of 2015, but continued her poor start to 2016, losing to Konta in straight sets, 4-6, 2-6 at the Melbourne Park, reports Xinhua.

Williams was almost bageled in the second set by a relentless Konta, who forced the seven-time Grand Slam winner across the court, but managed a mini-fight back before falling after one hour and 19 minutes.

Konta, 24, admitted her lead-up form wasn't the best, despite playing at two tournaments before here.

Konta could face China's No.1 ranked player Zheng Saisai in the second round. Zheng faces German Carina Witthoelt later on Tuesday.
