Blasting 31 winners, including 19 aces, to 17 unforced errors, No. 1 Serena Williams of the United States ousted No. 16 Maria Sharapova of Russia on June 28, 2010. The final score was 7-6 (9), 6-4.

Since winning the Wimbledon singles title in 2004, Maria Sharapova has twice made it to the semifinals but has exited in the second round each of the last two years. This time she bowed out in the fourth round.

Despite hitting 85 winners, including 38 aces, to just 33 unforced errors and winning more total points than his opponent (199 to 196), No. 5 Andy Roddick was an upset victim on Day 7. Unseeded Yen-Hsun Lu of Taipei earned a 4-6, 7-6 (3), 7-6 (4), 6-7 (5), 9-7 victory.

In his Wimbledon singles appearances the previous six years, Yen-Hsun Lu of Taipei lost four times in the first round and twice in the second round. Now he's into the quarterfinals. Lu broke American Andy Roddick just once in the match, which lasted four hours and 36 minutes, but pulled out a five-set victory.

Converting on all three of her break point chances in the fourth round, No. 2 Venus Williams of the United States pulled out a 6-3, 7-6 (5) victory over Australia's Jarmila Groth.

Jarmila Groth of Australia exited on June 28, 2010 with a straight-set loss against American Venus Williams in a match that lasted 97 minutes.

No. 1 Roger Federer of Switzerland converted six of 10 break point chances in a 6-3, 6-2, 6-3 victory over No. 16 Jurgen Melzer of Austria on June 28, 2010.

A semifinalist at the French Open this year, Austria's Jurgen Melzer couldn't match that feat at Wimbledon. But his fourth-round exit against Roger Federer still was his career best at the All England Club.

No. 2 Rafael Nadal of Spain hit 36 winners to just nine unforced errors in a 6-4, 6-2, 6-2 victory over France's Paul-Henri Mathieu on Day 7.

Matching his career best Wimbledon performance, France's Paul-Henri Mathieu lost to Spain's Rafael Nadal in the fourth round on June 28, 2010.

No. 8 Kim Clijsters of Belgium rallied from one set down to earn a 2-6, 6-2, 6-3 fourth-round Wimbledon victory over compatriot Justine Henin, the No. 17 seed. With the win, Clijsters improved her head-to-head record against Henin to 13-12.

Although she had fewer unforced errors than Day 7 opponent Kim Clijsters (1o to 23), Justine Henin also had fewer winners (18 to 22) in her three-set loss.

A ratio of 39 winners to 16 unforced errors helped No. 4 Andy Murray of Great Britain beat No. 18 Sam Querrey of the United States during their fourth-round match on June 28, 2010.

Prior to his run into the fourth round at the All England Club in 2010, American Sam Querrey never had made it past the second round at Wimbledon.

In fourth-round action on Day 7, No. 3 Novak Djokovic of Serbia battled No. 15 Lleyton Hewitt of Australia, ultimately pulling out a 7-5, 6-4, 3-6, 6-4 win to move deeper into the Wimbledon field.

After winning the Wimbledon title in 2002 and bowing out in the first round the next year, Australia's Lleyton Hewitt has exited in the semis once, the quarterfinals three times and the fourth round twice. In 2010, he added another fourth-round departure to that list.

No. 10 Jo-Wilfried Tsonga of France earned a 6-1, 6-4, 3-6, 6-1 victory over compatriot Julien Benneteau, the No. 32 seed, on June 28, 2010.

No. 32 Julien Benneteau of France converted two of three break point chances but was broken on six of nine chances by No. 10 Jo-Wilfried Tsonga, a fellow Frenchman.

In two previous Wimbledon appearances, Petra Kvitova of the Czech Republic didn't advance out of the first round. But with a dominant 6-2, 6-0 victory over No. 3 Carolina Wozniacki of Denmark on Day 7, she moved into the quarterfinals.

Winning a total of just 22 points to Petra Kvitova's 54, No. 3 Caroline Wozniacki was bounced out in the fourth round by Petra Kvitova.

Frustrated during his Day 7 match against David Ferrer, Robin Soderling took out some of that anger on his racket and finally captured a 6-2, 5-7, 6-2, 3-6, 7-5 win.

No. 9 David Ferrer of Spain broke on four of 11 chances but was broken on six of 16 chances by No. 6 Robin Soderling of Sweden in fourth-round action on June 28, 2010.

No. 9 Li Na of China needed just 67 minutes to dispatch No. 7 Agnieszka Radwanska of Poland by a 6-3, 6-2 score on June 28, 2010 at the All England Club.

Hitting just six winners to 12 unforced errors, Agnieszka Radwanska bowed out in the fourth round against Li Na on Day 7.

Trailing 6-1, 3-0 against No. 21 Vera Zvonareva of Russia on Day 7, No. 4 Jelena Jankovic of Serbia retired due to a back injury. It was the fourth time in her career that Jankovic lost in the fourth round at Wimbledon.

Blasting 18 winners to just five unforced errors, Vera Zvonarava beat Jelena Jankovic, 6-1, 3-0, on June 28, 2010.

Hitting 58 winners, including 20 aces, to 17 unforced errors, No. 12 Tomas Berdych of the Czech Republic moved into the Wimbledon quarterfinals. He beat Germany's Daniel Brands by a 4-6, 7-6 (1), 7-5, 6-3 score in the fourth round.

Germany's Daniel Brands won 126 total points to Tomas Berdych's 147 in a four-set loss at the All England Club on June 28, 2010.

Moving into the quarterfinals at a Grand Slam tournament for the first time in her career (she previously had never made it past the second round), Bulgaria's Tsvetana Pironkova picked up a 6-4, 6-4 win over No. 11 Marion Bartoli of France in fourth-round action on June 28, 2010.

Hitting 27 winners to 21 unforced errors wasn't enough to help France's Marion Bartoli, seeded 11th, advance into the quarterfinals. Her opponent, Bulgaria's Tsvetana Pironkova, hit 42 winners to 17 unforced errors in their Day 7 match.

Klara Zakopalova of the Czech Republic won just five of 25 points on her second serve en route to getting broken six times in a straight-set, Day 7 loss to Kaia Kanepi of Estonia.

The No. 2 men's doubles team of Americans Bob (right) and Mike Bryan earned a 6-2, 6-4, 7-6 (5) victory over Colin Fleming and Kenneth Skupski of Great Britain in the second round on June 28, 2010.

Looking for a little protection from the sun, a Wimbledon spectator on Day 7 fashioned a hat from newspaper.
