Roddick Wins, Agassi Defaults with Injury at Indian Wells

"When I woke up (Friday morning), it was blown up like a balloon, twice the size," Agassi said. "I was pretty shocked by what I saw. I can't bend it or move on it. It's just impossible for me to do anything. This is certainly not the way you want to see any tournament go, for the sake of all those involved."

Agassi said he was scheduled to have the toe undergo an MRI.

"I am disappointed that Andre had to pull out today," Hewitt said. "We have had a lot of good, tough matches in the past. I have to look at the positive side as well. This just put me into another semifinals at Indian Wells."

In the semis Hewitt will face Andy Roddick who came back for a 6-7(4), 6-4, 6-1 win over Carlos Moya.

"I felt good even after I lost the first set," said Roddick who threw down 13 aces and was effective at the net. "I was hitting the ball well and I'm glad I stuck it out."

Saturday's match-ups are (1) Federer vs. (14) Canas (the Argentine won their lone meeting in 2002) and (3) Roddick vs. (2) Hewitt (Aussie leads 5-1), and in the doubles final (1)Knowles/Nestor vs. (7) Arthurs/Hanley.
