The inaugural Cowboys Tennis Slam may not break the all-time tennis attendance record when it’s played on July 10 (that mark will likely be set two days earlier when Justine Henin and Kim Clijsters play in Belgium), but the pair of exhibition matches at Cowboys Stadium may be the first ever played in the end zone of a 100,000-seat football field.

Continuing his attempt to turn his $1.2 billion building into a mecca for all sports, Dallas Cowboys owner Jerry Jones will host a tennis exhibition in the Lone Star State six days after the end of Wimbledon. Serena Williams, Maria Sharapova, Andy Roddick and John Isner will play a pair of best-of-three matches at the stadium in Arlington, which will be configured to seat 20,000 fans. A temporary court will be erected in the west end zone.

Two immediate questions come to mind:

1. Will Jones be able to sell 20,000 tickets to two tennis matches (one of which includes the relatively unknown John Isner)?

2. Can the 3 million square-foot stadium contain the grunting of Maria Sharapova?

PARIS (AP)—John Isner has lost in the third round of the French Open to Tomas Berdych, 6-2, 6-2, 6-1.

Isner’s defeat Friday left the United States with two players in the men’s draw—Andy Roddick and Robby Ginepri.

The No. 17-seeded Isner had 38 aces in his second-round win but only nine against Berdych, and he lost serve seven times. Berdych, who had 43 winners and 10 unforced errors, will play No. 4 Andy Murray.

PARIS (AP)—American Mardy Fish has lost a marathon second-round match at the French Open that took more than 4 1/2 hours to complete over two days.

Ivan Ljubicic  rallied Friday to win 6-2, 6-7 (8), 4-6, 6-2, 10-8. The match had been suspended overnight because of darkness at one set apiece.

When the 14th-seeded Ljubicic hit a backhand winner to reach match point, he shimmied his hips to celebrate. He then hit his 18th ace to seal the win.

Ljubicic won 34 of 54 points at the net.

Fish, who is from Tampa, Fla., was unseeded and is ranked 97th.

PARIS (AP)—American Robby Ginepri has reached the third round at the French Open for the second time in his career.

In a matchup of unseeded players Friday, the 98th-ranked Ginepri beat No. 60 Potito Starace of Italy 3-6, 6-4, 6-3, 6-3.

Ginepri, of Kennesaw, Ga., had lost in the first round at five of the previous seven Grand Slam tournaments. He also was a first-round loser in six of his first seven appearances at Roland Garros; the exception was in 2008, when he made it all the way to the fourth round.

Ginepri’s top showing at a major tournament was reaching the semifinals of the 2005 U.S. Open. He joins top U.S. man Andy Roddick in the third round at Roland Garros this year.

PARIS (AP)—Fernando Gonzalez of Chile has been upset in the second round of the French Open, losing to unseeded Alexandr Dolgopolov Jr. of Ukraine in straight sets.

Playing in his first Grand Slam tournament, the 56th-ranked Dolgopolov beat the 12th-seeded Gonzalez 6-3, 6-4, 6-3 on Friday. It’s Dolgopolov’s first career victory over a player ranked in the top 20.

Gonzalez was a semifinalist at Roland Garros last year, and he was the runner-up at the 2007 Australian Open.
