NEW YORK (Reuters) - David Ferrer battled his way into the quarter-finals of the U.S. Open on Monday with a hard-fought 7-6(2) 3-6 7-5 7-6(3) win over Serbia's Janko Tipsarevic.
Ferrer, seeded fourth, retained his composure after dropping the second set to win a gruelling slugfest that took nearly four hours to complete after being moved to one of the smaller showcourts because of a lengthy rain delay.
