Katie Swan's run in the girls' singles came to an abrupt end after she retired from her first-round match against Mariam Bolkvadze.
Seeded at No.12, the 17-year-old British hopeful had to retire just after her serve was broken to leave her trailing 6-5 in the first set. She had been visibly uncomfortable for a couple of games.
The player called the trainer on and explained that she had severe pain in her lower leg. The decision was quickly made to retire and she shook Bolkvadze's hand before leaving the court, using her towel to wipe away the tears.
"I've been struggling with this injury for a few weeks and have been managing it," Swan told the BBC. She explained that the injury is a pre-stress fracture and there was "no point taking any risks".
This follows on from her disappointment in the Ladies' Singles where the world No.440 was knocked out in the first round by Hungary's Timea Babos. The match lasted just over an hour.
"Today it was just too painful and the doctor told me it's going to get worse if I keep playing so I stopped." She now plans to go back to America and "just try and get better as soon as possible."
Swan wasn't the only British player to face disappointment in the first round.
Alexis Canter put up a good fight against the boys' No.1 seed Stefanos Tsitsipas, losing the first set in a tie-break and the second one 7-5. Tsitsipas played a strong attacking game, winning 90% of points on his first serve. The world No.358 will face the American, Vasil Kirkov, in the next round.
Fourth seed Mate Valkusz had a tough first match against Estonia's Mattias Siimar, just managing to win the set 7-6. The second set was hard-fought and again went to a tie-break.
However, Valkursz pulled his game together and won it 6-1 to take the second set and the match in 1 hour, 25 minutes. He will be facing Britain's Luke Hammond in the next round.
Top seed Olesya Pervushina had a three-set match against Maria Mateas. Mateas won the first set 6-4 and then continued to dominate the first half of the second set before Pervushina pulled it back forcing the set into a tie-break.
Top seed then went from strength to strength, winning the tie-break and then winning the third and final set 6-2. Her serve was particularly impressive, with 16 aces compared to Mateas who did not hit any.
Third-seeded American Amanda Anisimova made quick work of Panna Udvardy, who she beat 6-2, 6-2 in just 46 minutes.
