I cannot find any fault at all with my game tonight

  Patrick Rafter

Ninth seed Patrick Rafter beat his American friend Todd Martin for the seventh time in 10 career meetings, earning his first ever straight-sets win in the series with a 6-4 6-2 night-time result.

Rafter ignored the distraction of a one-hour rain interruption in the first set, coming back and picking up where he left off when the pair went off with the Australian 4-3 up.

"We came back out and since Todd is a big guy, it takes a bit (of time) for him to get going," said Rafter.

"He was a bit flatter and I took advantage. I really hit the ball really well and tried to pick and choose shots to come in on. I cannot find any fault at all with my game tonight."

France's Fabrice Santoro beat Spaniard Albert Costa 7-5 2-6 6-3 and next plays Czech Bohdan Ulihrach, who triumphed 6-3 1-6 6-2 over Nicolas Escude of France.
