Wimbledon:Lleyton Hewitt showed signs of a dramatic return to form with a thrilling 6-3 7-5 7-5 victory over fifth seed Juan Martin Del Potro today. The former Wimbledon champion had dropped out of world top 50 after he struggled to recover from a hip injury sustained last year.
However, the Australian showed few signs of weakness on Centre Court as he comprehensively outplayed the Argentine, who had been tipped by many to clinch his maiden Grand Slam title at the All England Club.
Del Potro missed six break point opportunities in the opening set while Hewitt fired down 13 aces in the first two, leaving his opponent struggling to force his way back.
The Australian will now face one of unseeded duo Philipp Petzschner or Mischa Zverev in the third round.
Andy Roddick moved into the third round with a 6-4, 6-2, 3-6, 6-2 victory over Russian Igor Kunitsyn.
Roddick cruised into a two-set lead against the Russian, but a lapse in concentration allowed his opponent to fight back and win the third.
The sixth-seed American hit 18 aces and lost serve only once on the way setting up a clash with No. 26 Jurgen Melzer of Austria in the next stage of the tournament.
Earlier seeded trio Tomas Berdych, Victor Hanescu and Jurgen Melzer all powered into the third round of Wimbledon with convincing straight-sets victories on day four.
Czech Republic's Berdych, seeded 20th at the All England Club, romped to a 6-2 6-4 6-4 victory over France's Paul-Henri Mathieu and will await the winner of Nikolay Davydenko and Victor Crivoi in the last 32.
Number 32 seed Hanescu from Romania was even more emphatic as he disposed of another Frenchman, Nicolas Devilder 6-2 6-3 6-1.
Next up for Hanescu is a third round meeting with either Thiago Alves or number eight seed Gilles Simon.
And Austrian Melzer, whose first round victory over Wayne Odesnik is being investigated following irregular betting patterns, also safely booked his place in the last 32.
The number 26 seed overcame German Benjamin Becker 7-6 6-3 7-6 and will face Igor Kunitsyn or Andy Roddick for a place in the last 16.
