CARLSBAD, California, July 30: Fourth seed Lindsay Davenport, who has had injury troubles recently, appeared pain free while trouncing fellow American Amy Frazier 6-3 6-1 in the second round of the $1 million Acura Classic on Tuesday.

Sixth seed Chanda Rubin also progressed with a 7-5 6-0 victory over Slovenia’s Tina Pisnik, setting up a third-round match against ninth seed Jelena Dokic of Yugoslavia, who toppled Spain’s Magui Serna 2-6 6-2 6-3.

It was then so painful during Wimbledon that, after she lost to Venus Williams in the quarter-finals, the three times grand slam champion mentioned retirement.

The fourth seed, who won the title here in 1998, dictated against Frazier, an opponent she has beaten in all nine of their meetings.

Pisnik used a wicked backhand slice and mixed up the pace of her shots early on against Rubin but, after leading 4-1 in the first set, the Slovenian won only one more game in the match.

Dokic also had problems against Serna, who moved the Yugoslav about the court. But the 2000 Wimbledon semi-finalist seized control in the third set, crushing first serves and returning big.
