Bernard Tomic's US Open main draw tilt has been derailed on a day of mixed fortunes for Australia's bulging qualifying contingent at Flushing Meadows.
The former world No.17, chasing his first main draw appearance in New York in nine years, was beaten 7-6 (7-4) 6-2 by the in-form Henrique Roca in the second round on Friday (AEST).
