BIRMINGHAM, England -- Lisa Raymond worked on her singles game Tuesday, beating Russia's Anastasia Rodionova 6-3, 6-3 in the second round of the DFS Classic.

Raymond, seeded sixth in this grass-court event leading to Wimbledon, is primarily a doubles player. She has four career singles titles and 38 in doubles, including three Grand Slams.

Raymond, ranked as high as 15th in 1997, began working with coach Andy Brandi this year.

"If I am playing well, I can cause trouble for anyone in the world (in singles)," the 29-year-old American said.

In other matches, fourth-seeded Elena Bovina of Russia was beaten 6-3, 6-3 by Shinobu Asagoe of Japan in the second round and Maria Vento-Kabchi of Venezuela defeated 12th-seeded Daja Bedanova of the Czech Republic 6-2, 4-6, 7-6 (2) in the first round.

Top-seeded Russian Elena Dementieva plays her first match Wednesday.
