PARIS — All that stands between Rafael Nadal and a fifth French Open title is the only player ever to beat him at Roland Garros.

Nadal and Robin Soderling won semi-finals yesterday to set up a tantalising rematch. Soderling pulled off a stunner when they met in the fourth round last year, and the upset remains Nadal's lone loss in 38 French Open matches.

Soderling, runner-up to Roger Federer in 2009, returned to the final by sweeping the last four games to overtake No. 15-seeded Tomas Berdych 6-3, 3-6, 5-7, 6-3, 6-3. Nadal then beat No. 22 Jurgen Melzer 6-2, 6-3, 7-6 (6).

Soderling has a knack for upsets in Paris — he beat Federer in the quarter-finals this week — and he'll be an underdog again Sunday.

The No. 2-seeded Nadal has won all 18 sets in this year's tournament, and he's 21-0 on clay in 2010. He seeks to become the second man to win at least five French Open titles. Bjorn Borg won six.

Nadal is bidding for his seventh Grand Slam title. If he wins, he'll reclaim the No. 1 ranking from Federer next week.

But Soderling's big serve and forehand make him dangerous, as he showed against Berdych. Temperatures in the low 80s made for fast court conditions, and the first men's semi-final quickly developed into a slugfest between two of the hardest hitters in tennis.

Most points were short, and rallies were usually restricted to big swings from the backcourt, with few slices, drop shots, lobs or volleys.

The No. 5-seeded Soderling hit 18 aces, 62 winners and 63 unforced errors. Berdych hit 21 aces, 42 winners and 41 unforced errors.

"It was really tough to play my game," Soderling said, "because he was hitting so hard."

Soderling's only other Grand Slam final was at Roland Garros last year.

"I was only thinking about getting through the first round. Now two weeks later, I'm in the final again," Soderling told the crowd after his win. "It's better than the best dream."

Like Berdych, Melzer was a first-time Grand Slam semi-finalist, and the Austrian was overmatched from the baseline. His double-fault gave Nadal the first service break at love in the sixth game, and the Spaniard seized control of the match.

There were few long rallies, and Nadal won almost all of them, forcing Melzer to play high-risk tennis.

Venus and Serena Williams won their fourth consecutive Grand Slam doubles title and 12th overall by beating Katarina Srebotnik and Kveta Peschke 6-2, 6-3. First-time Grand Slam finalists Samantha Stosur and Francesca Schiavone play for the title in women's singles Saturday.

In the Soderling-Berdych marathon, five sets of swinging from the heels came down to the last three games. Serving at 3-all in the final set, Berdych fell behind love-30 and tried a rare drop shot, but Soderling dashed forward and scooped out a backhand winner. Two points later, Berdych dumped a backhand in the net to lose serve.

Soderling rallied from love-30 to hold for 5-3. Then, on the second point of the next game, he dashed from one sideline to the other to whack his running forehand past Berdych.

"Greatest shot of the match," said fellow Swede and three-time French Open champion Mats Wilander.

Match point came moments later, and when Berdych pushed a weary backhand wide, Soderling covered his face with his hands as his accomplishment sunk in.

It was only the fifth five-set win in the Swede's career.
