MEMPHIS, Tennessee – Victoria Azarenka of Belarus claimed her second title of the season as Andy Roddick and Radek Stepanek booked a final showdown at this 1.22 million-dollar ATP and WTA hardcourt tournament.

Second-seeded Azarenka swept past top-seeded Dane Caroline Wozniacki 6-1, 6-3 to add the Memphis crown to the first career title she won in Brisbane last month.

The 19-year-old had reached four finals over her previous two seasons but didn't break through until the Australian Open tuneup.

After a disappointing showing in the Australian Open, where she retired from her fourth-round match against eventual champion Serena Williams due to heat-related issues, Azarenka rebounded here.

She didn't drop a set in her first three matches this week before needing three to beat sixth seed Sabine Lisicki in the semi-finals.

Wozniacki, 18, was looking for her fourth career title in her first final of the year.

In the men's semi-finals, US top seed Andy Roddick rallied to beat Australian Lleyton Hewitt 2-6, 7-6 (7/4), 6-4 in a showdown of former world number ones.

Roddick, who blasted half his 16 aces in the second set and six more in the third, advanced to Sunday's final for a 300,000-dollar top prize against Czech fifth seed Radek Stepanek, who eliminated Israeli qualifier Dudi Sela 6-3, 6-1.

Sixth-ranked Roddick, the 2002 Memphis winner, is 4-1 against Stepanek and improved to 4-6 against Hewitt with his third consecutive victory in the rivalry. They had not faced each other since 2006.

Roddick, seeking his 27th career title, has reached at least the semi-finals at all four events he has played in 2009 but has yet to claim a crown.

"I was lucky to get through," Roddick said. "He had me up against it for the better part of the match. I kind of just snuck out of the tiebreaker there, and I played my best tennis in the third set."

Hewitt, who had major hip surgery in August and has fallen to 103rd in the rankings, fired 14 aces in defeat.

He has not won an ATP event since March of 2007, but Roddick said the Aussie's return from injury was impressive.

"It’s another testament to Lleyton’s willpower, which I don’t think has ever been questioned in the first place," Roddick said.

"I played pretty well, served well for the majority of the first set," said Hewitt, whose week included an upset of third-seeded American James Blake.

"I returned especially well in the first set and gave myself some opportunities in the second set and couldn’t quite take the couple of break points I did have the opportunities. He came up with a couple of big shots at the right time," Hewitt said.

Stepanek, ranked 21st, won last week's ATP event in San Jose and has not lost a set this week. He ousted Sela in 58 minutes, never facing a break point in improving to 16-2 this season, the best start of the 30-year-old's career.
