Melanie Oudin-Jack Sock reach final

Melanie Oudin and Jack Sock could soon be U.S. Open champions.

The two up-and-coming American players are in the mixed doubles final, not exactly something they expected when they were waiting to hear if they'd even get a wild card into the draw.

"Crazy" is how Oudin describes it. Sock goes with "insane."

"Any Grand Slam final you get to is a great achievement, especially because mixed doubles is probably the last thing I thought I'd get to the final in, personally," Oudin said.

The 19-year-old Oudin was the darling of the 2009 U.S. Open, reaching the women's quarterfinals. The 18-year-old Sock earned his first Grand Slam singles victory in the first round this year before being eliminated by Andy Roddick.

"To be able to come out here and be playing at the end of the second week at the Open in any event, even mixed, is a lot of confidence," said Sock, who actually can already claim a U.S. Open title -- at the junior level, after winning last year's boys tournament.

After advancing by walkover in the semifinals Thursday, the two teenagers face eighth-seeded Gisela Dulko and Eduardo Schwank of Argentina for the championship.

They fought off a match point in the first round, then faced the top-seeded defending champs, Bob Bryan and Liezel Huber.

Playing with another young American, Ryan Harrison, in the second round last year, Oudin lost to them in a tiebreak. Sock told her, "We'll take 'em this year."

Not that he totally believed it.

"I'm not going to lie, Sock acknowledged Thursday. "I did not look past the second round too far."

He'd lost to the top-ranked Bryan brothers in men's doubles earlier this year, a "thrashing" that lasted 38 minutes.

"I think that included the warmup," Sock added.

But this time, Oudin and Sock beat Bryan and Huber in a tiebreak.

The two have only known each other since December.

"She was too big-time for me," Sock said.

Now he keeps Oudin relaxed with his joking on the court.
