Seven-time champion Roger Federer eased into the second round at Wimbledon, but world number two Rafael Nadal was forced to work harder to The Spaniard will face Lukas Rosol, who upset him in 2012, in the second round.
London: World number one Rafael Nadal buried the first round misery of his 2013 Wimbledon on Tuesday to set up a rematch with Lukas Rosol, the Czech who condemned him to a humiliating second round exit in 2012.
Second seed Nadal, fresh from his ninth French Open triumph and bidding for a 15th Grand Slam title, became only the 11th man to record 700 tour wins when he came back from a set down to beat Slovakia's world number 51 Martin Klizan, 4-6, 6-3, 6-3, 6-3.
The Spaniard, champion in 2008 and 2010, was knocked out in the first round at Wimbledon last year by Steve Darcis, a Belgian journeyman who hasn't won a match since.

Twelve months earlier, Rosol had stunned him in five sets, a shattering defeat which forced Nadal out of the sport for seven months to rest his battered knees.
"Rosol is a very dangerous player, very strong, very powerful shots from the baseline and I know I have to play very well if I want to have chances to win," said Nadal.
"The important thing is to fight, play with the right tactic and wait for the luck."
Roger Federer began his campaign for an eighth Wimbledon title with a 6-1, 6-1, 6-3 victory over Paolo Lorenzi, the hapless Italian who has now lost all of his 13 Grand Slam matches.
Fourth-seeded Federer, the 17-time major winner, had lost to Ukraine's Sergiy Stakhovksy in the second round 12 months ago for his earliest defeat at the tournament since 2002.
But there was never a hint of a repeat of that disaster on Tuesday as the 32-year-old Swiss took victory on a sixth match point having fired nine aces and 36 winners.
"It's always good to win the first round because the court can be slippery sometimes," said Federer, who goes on to face either Luxembourg qualifier Gilles Muller or Julien Benneteau of France for a place in the last 32.
Defeat for Lorenzi meant the 32-year-old has still to win a match at a Grand Slam in 11 years.
But his run of 13 defeats in 13 matches at the majors is not a record -- that statistic of shame belongs to Costa Rica's Juan Antonio Marin who lost all of his 17 matches at the majors.
Federer's compatriot, Australian Open winner Stan Wawrinka also reached the second round with a first win at the tournament since 2011.
Wawrinka, the world number three but seeded five at the All England Club in a reflection of his grasscourt struggles, fired 18 aces and 39 winners in a 6-3, 6-4, 6-3 win over Portugal's Joao Sousa.
Wawrinka, who has never got beyond the fourth round and was without a win in the tournament since 2011, tackles Taiwan's Lu Yen-Hsun for a place in the last 32.
Lleyton Hewitt, the 2002 champion, and like Federer playing his 61st major, beat Michal Przysiezny of Poland, 6-2, 6-7 (14/16), 6-1, 6-4.
French Open champion and fifth seed Maria Sharapova, who won her first major at Wimbledon as a 17-year-old in 2004, raced to a 6-1, 6-0 rout of British wild card Samantha Murray, the world number 247.
Sharapova, who was knocked out in the second round last year, next faces Swiss qualifier Timea Bacsinszky.
"There's always a bit more tension coming into the first round of a Grand Slam. It was such a quick turnaround. Just a couple weeks ago you're on the clay, coming onto the grass, with the new grass and new surface, it's a different feeling," said the Russian.
"But overall I am happy with how I progressed through the match, which was the important key."
Retired women's champion Marion Bartoli returned to Centre Court only to hear herself introduced as 'Maria' by a blundering announcer.
The Frenchwoman performed the coin toss ahead of the first round match between Sabine Lisicki, the German she defeated in the final last year, and Israel's Julia Glushko.
Lisicki, yet to get beyond the third round of any event in 2014, was untroubled against Glushko, the world number 79, winning 6-2, 6-1 in just 57 minutes.
Polish fourth seed Agnieszka Radwanska, the 2012 runner-up, beat Romania's Andreea Mitu 6-2, 6-1.
Top seed and five-time champion Serena Williams starts her campaign against Anna Tatishvili, the former Georgian player who has switched allegiance to the United States.
Michelle Larcher de Brito, who shocked Sharapova last year, defeated two-time major winner Svetlana Kuznetsova, the Russian 28th seed, 3-6, 6-3, 6-1 while Italian 14th seed Sara Errani lost to France's Caroline Garcia 2-6, 7-6 (7/3), 7-5.
