WIMBLEDON, England, June 27 (UPI) -- World No. 1 Ana Ivanovic was defeated in straight sets Friday by Jie Zheng in third-round play at The Championships at Wimbledon.

Ivanovic, a finalist at the 2008 Australian Open and the winner at the French Open, was routed, 6-1, 6-4. Ivanovic barely survived a tough match in the second round but was dominated by the 133rd-ranked Zheng.

Zheng moves into Wimbledon's fourth round and a match against 15th-seeded Agnes Szavay, who was a 7-6 (7-5), 2-6, 6-2 winner over Anabel Medina Garrigues in her third-round match.

The fourth round will pair two Americans against each other as Bethanie Mattek upset 11th-seeded Marion Bartoli, 6-4, 6-1. That gave her a shot at sixth-seeded Serena Williams, who was a 7-6 (7-5), 6-1 winner Friday over No. 29-seeded Amelie Mauresmo. Both Bartoli and Mauresmo were hampered in the second sets by injury.

No. 4-seeded Svetlana Kuznetsova and eighth-seeded Anna Chakvetadze were straight-set, third-round winners. Kuznetsova breezed past Barbora Zahlavova Strycova, 6-2, 6-4, and Chakvetadze was 6-4, 6-3 winner over Evgeniya Rodina.

Also Friday, 14th-seeded Agnieszka Radwanska took out Anastasia Pavlyuchenkova, 6-3, 6-2, and No. 18 Nicole Vaidisova defeated Casey Dellacqua, 6-2, 6-4.

The fourth-round pairings have Kuznetsova going against Radwanska and Chakvetadze playing Vaidisova.

PARIS, June 27 (UPI) -- England's David Lynn and Spain's Pablo Larrazabal are co-leaders after 36 holes at the European Tour's Open de France golf tournament in Paris.

They are both at 7-under-par 135 after two rounds.

Lynn, who began the day in a tie for 28th place, shot up the leader-board Friday with a 6-under 65 while Larrazabal, the first-round leader by one stroke, managed 1-under 70.

Lynn sank a shot from the bunker for birdie at No. 18 to grab a piece of the 36-hole lead.

When I made a double bogey seven on the ninth I wasn't happy at all, but I knew that I was playing well, Lynn said.

I started off a little tired because I was watching the match and I was a little nervous so made a bogey on the first, Larrazabal said after a windy day at Le Golf National golf course.

Colin Montgomerie (68) and Lee Westwood (68) joined a group of five players tied for third place at 5-under 137.

WIMBLEDON, England, June 27 (UPI) -- Mario Ancic beat No. 5-seeded David Ferrer in four sets Friday, adding to the high-profile upsets in the men's draw of The Championships at Wimbledon.

With half the third round still to be played, just three -- No. 1 Roger Federer, No. 2 Rafael Nadal and No. 8 Richard Gasquet -- of the top nine men's seeds remain. Nadal and Gasquet play third-round matches Saturday.

Ancic took a spirited 6-4, 6-4, 6-7 (5-7), 7-6 (7-3) match from Ferrer. The world No. 5 was down two sets but battled gamely and took the third set in a tiebreaker. He forced another tiebreaker in the fourth set but Ancic quickly established control and was able to put the match away.

Federer, looking for a sixth consecutive Wimbledon title, was workmanlike in a 6-3, 6-3, 6-1 win over Marc Gicquel in his third-round match. He heads into a round-of-16 pairings against 20th-seeded Lleyton Hewitt, who took out Simone Bolelli, 6-1, 6-3, 7-6 (7-2), in the third round.

No. 11-seeded Tomas Berdych joined the other ousted high seeds on the sidelines after 22nd-seeded Fernando Verdasco took a 6-4, 6-4, 6-0 decision. Verdasco goes against Ancic in the fourth round.

No. 13-seeded Stanislas Wawrinka earned a spot in the fourth round by advancing over Mischa Zverev. Wawrinka was ahead 7-5, 6-1 Zverev retired. Marin Safin took out 29th-seeded Andreas Seppi, 7-6 (7-5), 3-6, 7-6 (7-3), 6-4, and next draws Wawrinka.

The fourth fourth-round match in the top half of the draw has No. 10-seeded Marcos Baghdatis playing No. 31 Feliciano Lopez. Baghdatis defeated Simon Stadler, 7-6 (7-2), 6-4, 6-2, while Lopez eliminated Bobby Reynolds, 6-4, 7-5, 4-6, 6-4, in Friday. Reynolds was the last American in the men's draw.

NEW YORK, June 27 (UPI) -- O.J. Mayo and Kevin Love, two of the top picks in this year's NBA draft, are part of an eight-player trade between Minnesota and Memphis.

Mayo, a 6-foot-5 inch guard for Southern California and the third overall selection by the Timberwolves, was dealt to the Grizzlies with guards Marko Jaric and Greg Buckner and forward Antoine Walker.

Love, a 6-foot-10 inch power forward from UCLA and the draft's fifth overall pick by the Grizzlies, went to Minnesota along with shooting guard Mike Miller and forwards Brian Cardinal and Jason Collins.

Both Love and Mayo were freshmen last college basketball season.

I just wanted to hear my name called and be part of the NBA, Mayo said shortly after he was picked Thursday by the Timberwolves. It didn't matter if it was a big-market organization, small-market, medium-market.

Jaric averaged 8.3 points a game last season, Bruckner averaged 4 points while playing for his fourth NBA team and Miller has a career average of 16.4 points a game.

LONDON, June 27 (UPI) -- The sailing venue for the Beijing Olympic Games is threatened of being clogged by an algae outbreak, Chinese officials admitted.

The report by The Telegraph in London said that Qingdao Bay has been hit by the worst algae blight in living memory. The environmental problem has forced officials to order an emergency cleanup of threatened regatta routes.

It's a climatic disaster and we can only hope the heavens will be kind to us in August, Wang Haitao, Beijing's Olympics spokesman told The Telegraph. We're doing all we can with our arms full and by the boatload. All you can see is fishing boats along the coast.

Spinach-sized clumps of algae have prevented row boats to cross the bay located on the western edge of the polluted Yellow Sea.

About 1,000 fishing boats are being used to scoop up the algae and the Qingdao Weather Bureau says warmer waters, increased rainfall and high levels of nutrients in the ocean brought about the algae explosion along vast stretches of the 500-mile coastline.
