NEW YORK -- David Ferrer made it into his second U.S. Open semifinal Thursday, bringing eighth-seeded Janko Tipsarevic to his knees more than once in a 6-3, 6-7 (5), 2-6, 6-3, 7-6 (4) quarterfinal victory in Arthur Ashe Stadium.
Ferrer, from Spain, will play the winner of the last men's quarterfinal between defending champion and second-seeded Novak Djokovic and seventh-seeded 2009 champion Juan Martin del Potro. That match was scheduled to be played later Thursday. Third-seeded Andy Murray and sixth-seeded Tomas Berdych have already earned their Saturday semifinal places.
