Former world No 1 made to work for his victory though.
Rafa Nadal saw off the challenge of Argentina’s Carlos Berlocq in three sets to make it through to the semi-finals of the Brazil Open.
The 26-year-old Spaniard, ranked number five in the world, won his singles quarterfinal match 3-6, 6-4, 6-4 in two hours 24 minutes against the 30-year old Argentine, ranked 78th in the world.
Nadal will face off in Saturday’s semifinal against another Argentine, Martin Alund, who earlier Friday defeated Filippo Volandri of Italy 7-5, 7-6.
In another quarter-final earlier Friday, Argentine David Nalbandian beat Spaniard Nicolas Almagro, the winner of the Brazil Open last year.
Nalbandian will contest Saturday’s other semifinal against Italian Simone Bolelli who ousted Argentine Juan Monaco.
Berlocq dominated the first set, breaking Nadal’s serve twice before prevailing 6-3, and serving several aces during the match.
But the Spaniard, who enjoyed the raucous support of the crowd at Sao Paulo’s Ibirapuera gymnasium, later said he never thought of losing the contest.
“I was able to be solid with my serves and take advantage of the fact that he (Berlocq) did not return well,” he said.
Nadal, who is recovering from a knee injury, at times appeared a bit tentative but used powerful serves and brilliant drop shots to tame his opponent.
“For me every victory is important. It is the moment to have the necessary humility to fight in every match as I did today,” he said.
“It’s the first match I win in three sets here. It helps me get better physically, It helps me regain my self-confidence,” Nadal added.
is the top seed in this $455,775 tournament, his second comeback event after a seven-month absence.
Last week, he competed in the Vina del Mar Open in Chile, losing the singles and doubles finals Sunday.
Nadal has claimed seven of his 11 Grand Slam titles on the clay courts of Roland Garros. He won the Brazil Open in 2005, when it was held in Costa do Sauipe in eastern Bahia state.
Last year, the tournament was moved to Sao Paulo.
The Brazil Open is part of the Latin American clay court circuit, along with the Vina del Mar event and the Mexico Open, in Acapulco, where Nadal plans to play later this month.
The three low-profile Latin American events are routinely ignored by the world’s top three players: Novak Djokovic, Roger Federer and Andy Murray.
