Memphis, March 1:

Robin Soderling upset top-seeded Andy Roddick 7-6 (6), 6-3 in the Regions Morgan Keegan Championships quarter-finals on Friday, ending the American’s bid to win in consecutive weeks.

Roddick won at San Jose last week and went into the quarter-final 10-1 this season, ranked sixth in the world. Soderling had been only 7-19 against top 10 players, a record that included a victory over No 7 Richard Gasquet this week.

But the eighth-seeded Swede served up 16 aces and won all but nine points on his serve and 14 of 18 on his second serve. Soderling did not face one break point and hasn’t been broken in three matches.

Swedish veteran Jonas Bjorkman saved a match point in beating American teenager Donald Young 1-6, 6-2, 7-6 (6) and will play Steve Darcis of Belgium, a 6-1, 6-0 winner over Benjamin Becker of Germany.

On the women’s side, fourth-seeded Lindsay Davenport beat Marina Erakovic of New Zealand 6-0, 6-3. Davenport will meet fifth-seeded Olga Govortsova of Belarus in the final of the Cellular South Cup. Govortsova downed Shahar Peer of Israel 6-3, 3-6, 6-4.
