NEW YORK — Persistence finally paid off for Kevin Anderson as the towering South African prevailed in a slugfest with Andy Murray to reach the quarter-finals of the U.S. Open on Monday while another tennis giant John Isner was slain by Roger Federer.
Two David v Goliath matchups, however, ended all too predictably as 97th ranked British qualifier Johanna Konta saw her Flushing Meadows joy ride ended 7-5 6-3 by fifth seeded Czech Petra Kvitova and 68th ranked American Donald Young ran out of comeback magic in a 6-4 1-6 6-3 6-4 loss to fifth seed Stan Wawrinka of Switzerland.
