Conor Niland and Louk Sorensen are just two wins away from the US Open after recording victories on the opening day of qualifying at Flushing Meadows.
Limerick's Niland recorded a comfortable straight-sets victory against Pavol Cervenak.
Niland, currently ranked 199 in the world, cruised past Cervenak 6-1 6-4 to set up a second round encounter against Chinese Taipei’s Tsung-Hua Yang.
The Irish number one reached the first round at Wimbledon earlier this year.
Meanwhile, Louk Sorensen, who briefly called time on his career earlier this year, has joined Niland in the second round after a surprise 7-6 6-4 win over Spain’s Arnau Brugues-Davi.
Sorsensen will play Alex Kuznetsov or Gastao Elias in the next round.
Sorensen has been blighted by injuries in recent seasons and has seen his ATP ranking plummet from a career high of 213 to 614, but the man from Stuttgart has been buoyed by a number of encouraging results since his return to the tour.
