NEW YORK, Sept. 2 (UPI) -- Andre Agassi advanced to the third round of the U.S. Open Thursday when Florian Mayer of Germany retired with a hamstring injury in the fourth set.
The sixth-seeded Agassi was ahead 7-5, 2-6, 6-2, 1-0 when Mayer was forced to quit. Mayer's retirement came after he played an almost perfect second set that appeared to give him a chance for the upset.
Mayer, 20, reached the Wimbledon quarterfinals two months ago.
Fifth-seeded Tim Henman of England also made it to the third round by outlasting French qualifier Jerome Golmard, 6-2, 6-4, 4-6, 7-6 (7-1).
Earlier in the day, surprise French Open titlist Gaston Gaudio was ousted by Swede Thomas Johansson, 6-3, 2-6, 6-4. Johansson missed all of the 2003 season while recovering from a knee injury after winning the 2002 Australian Open.
In other action, No. 15 Paradorn Srichaphan of Thailand defeated American Paul Goldstein, 6-4, 7-6 (7-4), 6-0; and No. 16 Andrei Pavel of Romania dismissed Spaniard Fernando Verdasco 7-5, 6-3, 7-6 (7-2).
