Roger Federer needed four sets to outlast Sam Groth and book his place in the round of 16 at Wimbledon as Rafael Nadal’s-conqueror, Dustin Brown, could not build on his previous success.
The Swiss, 33, fought back from an opening set loss to snatch a 6-4 6-4 6-7 (5-7) 6-2 win and set up Spanish 20th seed Roberto Bautista Agut in the next round.
World No. 66, Groth, fired the second-fastest serve in Wimbledon history measured at 147mph, but it was not sufficient to outclass seven-time winner, Federer.
German qualifier Brown was forced to kiss the dust by Serbia’s 22 seed Viktor Troicki, losing 6-4 7-6 (7-3) 4-6 6-3 in their third round clash.
The 30-year-old dreadlocked sensation thrilled the crowd at court three with some unconventional shots, but could not progress further at the SW19.
World No. 5 Caroline Wozniacki advanced into the fourth round at Wimbledon with straight sets victory over Italy’s Camila Giorgi.
Dane, Wozniacki needed just 72 minutes to seal a 6-2 6-2 win and stay on till the second week of the championship.
The former world No. 1 will face 20th seed Garbine Muguruza, who beat 10th seed Angelique Kerber 7-6 (14-12) 1-6 6-2.
Switzerland’s Timea Bacsinzky knocked out 2013 finalist Sabine Lisicki 6-3 6-2 to advance to her first Wimbledon round of 16.
American Madison Keys is also through to the second week at the All England Club for the first time after a 6-4 6-4 win over Getmany’s Tatjana Maria.
