(6) Juan Martin Del Potro d. Daniel Koellerer 6-1, 3-6, 6-3, 6-3
Aside from a dismal second set, Del Potro otherwise rolled over Koellerer in the U.S. Open second round on Sunday. The world no. 6 seeded two hours and seven minutes to set up a fourth-round showdown against Juan Carlos Ferrer. Del Potro dominated the first, but--perhaps due to a false sense of secuirty--he completely collapsed in set two. He sprayed 19 unforced errors, put in less than half of his first serves, and was broken an incrreible four times as Koellerer jumped all over his secnd offerings.
Not surprisingly, the shock second-set defeat only seemed to wake up the 20-year-old. Del Potro cleaned up his game and improved his serving en route to easing past Koellerer in sets three and four. The unnheralded Austrian fought hard and did well to keep it competitive while firing 20 winners and 28 unforced errors. Del Potro struck 56 winners and made 44 mistakes (in other words, just 25 errors in addition to those in the shockingly poor second set. Next up for the Argentine is Juan Carlos Ferrero.
Juan Carlos Ferrero d. Gilles Simon 1-6, 6-4, 7-6(5), 1-0, ret.
Ferrero advanced to the fourth round of the U.S. Open on Sunday afternoon when Simon retired early in the fourth set due to a knee injury. For a while it looked like it would be Simon to cruise into the second week in New York, as he dominated the first set in 20 minutes. From then on, however, the roles were reversed. Ferrero could not keep the ball in play while Simon could not miss in set one, but Ferrero's game turned around as Simon's collapsed the rest of the way.
It did not help the ninth-ranked Frenchman that his long-standing knee injury flared up again. When he lost a tight third-set tiebreaker, he knew he had know chance of playing--and winning--two more sets of grueling baseline tennis. Simon called it quits one game into the fourth frame of play, sending Ferrero--the 2003 Open runner-up--into a showdown with Del Potro.
