Jamie Baker progressed in French Open qualifying on Tuesday but fellow Britons James Ward and Josh Goodall fell at the first hurdle.
Baker saw off Germany's Peter Torebko 6-4 7-6 (7/4) at Roland Garros to move into the second round. He will need to win three matches if he is to join Andy Murray in the main draw.
Next up for the British number three will be a meeting with Spaniard Daniel Munoz-De La Nava.
However, Goodall, ranked 22 places lower than Baker at 228, was beaten in a tight match with Hiroki Moriya, the Japanese coming from a set down to win 6-7 (5/7) 7-5 7-5.
Ward, the 29th seed, was then beaten 6-2 4-6 6-3 by American Denis Kudla.
Meanwhile, on the women's side, British number three Heather Watson will open her qualifying campaign against Canada's Sharon Fichman on Wednesday.
Like Watson, Laura Robson is seeded for the qualifying competition. She meets Spain's Estrella Cabeza Candela.
The other British entrant, Naomi Broady, faces a tough opener. She's up against former world number 35 Sesil Karatantcheva. The Kazakh was a French Open quarter-finalist back in 2005.
