Venus Williams, Ana Ivanovic and Marat Safin have all cruised to straight-set victories.
Venus looked a little shaky — she had six double faults — and Ivanovic was broken early before both settled down and steamrolled their opponents.
The most impressive performance of the afternoon goes to American Robby Ginepri, now ranked 64th, who won a blowout match 6-0, 6-3, 6-1.
Ginepri was a semifinalist in 2005 (he lost to Agassi) and was inside the Top 15 before turning in a 9-16 performance this year and falling to pieces.
According to this very good profile in the Atlanta Journal Constitution, Ginepri a month ago named as his coach Jose Higueras, the guru who once guided Pete Sampras, Michael Chang and Jim Courier.
