There were no easy throughs for the Spanish Kings, however, as Moya had to battle from one set down to claim a thrilling three-set win, and Ferrero, also former French Open champion, stumbled to beat Russian Dmitry Tursunov 6-4, 7-6 (4).

Moya, who overcame a slow start to win 3-6, 6-3, 6-2, was broken twice by the 106th-ranked Stefan Koubek of Austria to lose the first set before finding back his trademarked baseline play to come back. He will take fourth seed Thomas Johansson in the quarter-finals after the Swede beat Jarkko Nieminen 6-4, 6-4 with wasting only one match point.

Ferrero was taken one hour and 49 minutes to wrap up the tiebreaking win against Tursunov, during which the 23rd-ranked Spaniard was angered by the chaired umpire after being ruled out baseline play on break point in the second set.

Taking the first set with ease, the clay specialist Ferrero, who claimed the Grand Slam title at Roland Garros in 2003, stroke the ball to the far angle but the umpire ruled it off the bound.

Winning the controversial break point, the 135th-ranked Tursunov tied the second set on 5-5 and overtook the lead 6-5 with his own server before the Spaniard forced a tiebreaker by saving a set point to win the 12th game.

Trailing as much as 4-1, Ferrero came back to win the tiebreaker 7-4 with a 6-0 run, where Tursunov double-faulted to grant the tie on 4-4.

"It's a close game, my opponent is fast and well-controlled, and fortunately my fitness is good too and I won the match," said the 25-year-old Spaniard who was seeded 6th for the annual competition.

"I hope I can win the China Open, but victory is not always following your wish. There're many strong players from Spain, I do wish the winner is me and I think I gonna make it only if I played my best," said Ferrero.

Ferrero will next play third seed David Nalbandian after the Argentine made short work of qualifier Amir Hadad of Israel 6-4, 6-0 in a later second round matchup.

"Nalbandian is a good player, and he played well in the U.S. Open. I must boast my confident to face him," commented Ferrero.

Spain's tennis upstart Nadal flipped to a 6-2, 6-4 victory over Wang Yeu-Tzuoo from Chinese Taipei in one hour and 28 minutes, but losing concentration had cost the 19-year-old an otherwise perfect China Open debut.

The top seed broke his 100th-ranked opponent twice to jump to a4-0 lead short into the match, which had been pushed back from Monday to Wednesday as Wang delayed three days from the original schedule of his arrival to Beijing from Turkey.

But for a moment, Nadal lost his focus and granted the Chinese Taipei player slim hopes of comeback, being broken in the sixth game following Wang won his third server.

The world number two recovered quickly from floppiness before wrapping up the set 6-2 despite two double-faults in his own servers.

Leading as much as 4-0 in the second set, Nadal again rule out a turning-around though the top Chinese player Wang cut the games deficit to 5-4, and won the set 6-4 as Wang backhanded the ball wide after forcing two deuces.

"I had got my chance, but I failed to make win out of it," said the 20-year-old Wang who committed 12 unforced errors throughout the match. "I broke him just because he made more errors in those games."

Nadal had reckoned it an easy match, and the little twist did not upset the confident Spaniard.

"I think I'm being well, especially in first set. I'm playing better than US Open. Though I've lost my concentration during the match and gave up my servers on it, but I'm still confident," said the 19-year-old who will next play the second round against Justin Gimelstob from the United States.
