Andre Agassi made a stunning return to action on Tuesday when he routed Frenchman Jean-Rene Lisnard in the first round of the Mercedes-Benz Cup. The 35-year-old, seeded number one in LA, had been sidelined for the last two months with a sciatic nerve problem.
But he made quick work of his lucky loser opponent, dominating 6-1 6-0 to set up a second-round match with compatriot Kevin Kim.
Earlier, third seed Nicolas Kiefer retired from the event due to illness.
The German was trailing wildcard James Blake 2-3 when he quit, and Blake will now face fellow American Robby Ginepri, who ousted Australian Wayne Arthurs 6-4 6-4.
Fifth seeded Taylor Dent and unseeded Mardy Fish, scheduled for Tuesday's last match, withdrew a few hours before they were to take the court.

Dent pulled out because of lingering effects of heat illness that caused him to retire in Sunday's final at Indianapolis, and Fish withdrew because of a sore right wrist.
Defending champion Tommy Haas, playing for the first time since tearing a ligament in his right ankle at Wimbledon, was a 6-4 6-4 winner over Ivo Karlovic.
Agassi made the perfect comeback with a 47-minute demolition of Lisnard.
"Certainly to come out here for the first match in such a long time, I could never have expected or hoped for that standard and to be that comfortable early on," said Agassi.
"I just settled in early. I felt like I was covering good court.
"I was very happy with all aspects of my game. I was expecting the nerves, which I did have, but nerves go away quickly when you get up two breaks immediately, which I did.
"I was expecting to make some bad decisions in shot selection, to be struggling a little bit.
"I was expecting to be sort of like a deer in the headlights and watch a few too long and not react as quickly as I knew I could have."
