At the Australian Open today
At the U.S. Open, Andre Agassi wasn't too concerned about fellow American Taylor Dent. That changed after they met in the fourth round. Although Dent retired from the match with an injury, Agassi's attitude had changed.
"I was surprised at how frustrating he was making it for me to hold," Agassi said afterward.
Dent is going to do his best to make things frustrating for Andy Roddick today in what is sure to be a hard-serving battle. Both have recorded serves over 144 mph in competition.
Although Roddick is the No. 1 player in the world, it's Dent who might have the crowd advantage. His father, Phil Dent, is Australian and reached the final at the Aussie Open in 1976.
