Defending Australian Open champ, Andre Agassi had an easy quarter final match against Frenchman Sebastien Grosjean, taking him through to the semi-finals.
Agassi broke Grosjean's serve in the first game and the Frenchman required treatment from his trainer for a pulled muscle early in the match. Grosjean retired during the second set, and Agassi won 6-2 2-0.
"Today I was executing the ball well, the first day we've had some pretty warm weather in a while so it snuck up on both of us," Agassi said. "I managed to get the upper hand there..., it's just unfortunate that it ended that way today."
