Wimbledon, the oldest tournament in tennis, the most famous tournament in tennis. The tournament in which at the start of the second week on Monday, there were numerous Swedes and Serbs and Russians and Swiss in singles. And four Americans.

Before early afternoon, the number was reduced to three. Oudin (pronounced Ooh-DAHN), the 17-year-old from the suburbs of Atlanta, was beaten in the fourth round by Agnieszka Radwanska of Poland, 6-4, 7-5.

The number was reduced, but America's hopes were not. Maybe after the great Venus and Serena Williams, now in their late 20s, somebody holding a U.S. passport will again be a women's champion. Maybe somebody after the retired Pete Sampras and Andre Agassi there will be a men's champion.

The major leagues have become the Caribbean league. "No rich kid will ever be a ballplayer," Joe DiMaggio was to have said half a century past. "You've got to be hungry."

Meaning you have to grind and sweat and practice. Meaning you have to give up the mall for the playgrounds. Or sandlots. Or clearings amongst the palm trees.

Baseball is the domain of the Dominicans and Venezuelans because they have earned their way.

Tennis belongs to the Eastern Europeans -- at the French Open, there were 25 women whose name ended in "-ova," the label of an unmarried female in those nations. "They want to succeed," a U.S. Tennis Association official made clear of the Serbs and Russians and Czechs.

So does Melanie Oudin, who although of French descent, calls herself "totally American." She's only wanted one thing as she aged: to become better than anyone else.

First you to have to make the commitment. Then you have to make progress. Oudin has done both.

"My goal," said Oudin, "has always been to be No. 1 in the world someday. But it's going to take a lot more work, and I'm going to have to get better and better. But I'm willing to work on it."

She began Wimbledon at 124 in the women's rankings. Now she's in the top 100. But is it only a temporary burst? Does she continue to move up, beat the Hantuchovas and Petrovas and Dementievas, or simply flame out and slip again into anonymity?

"I've always been mentally tough on court," said Oudin. That's a start. And she's quick. But at 5-foot-6, Oudin lacks a big serve and power strokes at the moment.

"She doesn't have weapons," said Jelena Jankovic, a former No. 1, after Oudin beat her.

She has the desire; as DiMaggio might have said, the hunger. She knew what she wanted from the time she was 12 and attending the U.S. Open at Flushing Meadow. "I always said I wanted to play in the pros there," was Oudin's recollection. No less significantly, she was playing in the pros here, at the 123rd Wimbledon.

"I didn't expect it coming into this tournament," said Oudin in reflection. She had to survive two match points the first round of qualifying. Then she beat three women ranked above her, two of them, Sybille Bammer and No. 6 Jankovic, seeded the first week of play.

"I'm happy with the way I fought here. I gave everything I have. I'm still the same person, but I think I've improved this week. I think I've gotten better as a player, but I'm looking forward to keep going."

So is the United States. So are ESPN, NBC and CBS, which televise the Grand Slam tournaments. So are tennis people around the globe because they know an American presence benefits the sport.

Oudin could be playing in the juniors. A year ago she was, but lost to Laura Robson of England. This time, Robson, in the main draw, was beaten in the first round while Oudin, the home-schooled munchkin from Georgia, made it into the fourth. And made it into the headlines.

"I'm, like, disappointed I lost today," said Oudin. One step more and she would have been in the quarter-finals. But already she has taken some very large steps.

"I'm very proud of myself, how I did here," said Oudin. "Now I can play with these girls, and this is what I want to do and what I want to be.

"If you really want this, I don't think anything will distract you. There are different things that I've wanted to do, but this is worth it to me. This is what I've always wanted."

What she wants is what America needs: a new face at the summit of tennis.
