MELBOURNE, Australia -- Women's top seed Maria Sharapova edged out compatriot Vera Zvonareva 7-5, 6-4 to reach the Australian Open quarterfinals for the third time in her career Monday.

Sharapova, 19, clinched a tight opening set to take the initiative and despite recovering from being 5-2 down in the second, the 22nd seed could not fend off Sharapova, who won in one hour and 46 minutes at Rod Laver Arena.

Sharapova, who will regain the world No. 1 ranking at the end of the tournament, served solidly in the first and did not concede a break point throughout.

She sealed her own break with a crunching forehand drive and Zvonareva swiped her racket at the floor in frustration.

Sharapova took the momentum into the second set, breaking in Zvonareva's first service game and making it a double break when a double fault gave her a 5-2 advantage.

Zvonareva briefly threatened a revival when she broke Sharapova's serve and then held her own to pull back to 5-4, but the U.S. Open champion clung on, sealing victory with another forehand winner.

Sharapova, a semifinalist the last two years here, plays her third, fellow Russian of the tournament in the last eight when she faces 12th seed Anna Chakvetadze.

In the men's draw, third-seeded Russian Nikolai Davydenko wore down Czech Tomas Berdych to seal a 5-7, 6-4, 6-1, 7-6 victory and reach the quarterfinals.

Davydenko was outplayed by the 13th seed in the first set but his unerringly consistent game gradually nullified Berdych, and he clinched victory on his fourth match point in exactly three hours.

Berdych, 21, saved three match points at 5-6 in the fourth set to force the tiebreak but he made two unforced errors to give Davydenko match point and another mistake sent the third seed through to the last eight.

Davydenko will play German Tommy Haas for a place in the semifinals.

Second seed Rafael Nadal won an epic clash with Briton Andy Murray 6-7, 6-4, 4-6, 6-3, 6-1 to set up a quarterfinal encounter with 10th seed Fernando Gonzalez.

The 15th-seeded Murray, 19, stood up to the Spaniard's bludgeoning groundstrokes in the first set and controlled the tiebreak to take it 7-3.

Nadal came from a break down to level the match and made an early break in the third but Murray refused to lie down, taking the Spaniard's serve twice to clinch the set.

Murray wasted chances to break Nadal early in the fourth set and the world No. 2 engineered two breaks of his own to level the fluctuating night match at Rod Laver Arena.

Nadal, 20, broke for a 2-0 lead in the decider and romped through the final set to seal victory in three hours 51 minutes and reach the Australian Open quarterfinals for the first time.
