Three-time Grand Slam winner Stan Wawrinka has exited Wimbledon in the second-round, losing out to American Reilly Opelka in five sets.
21-year-old Opelka, who stands at 6'11", battled back from losing the first two sets to register a 7-5 3-6 4-6 6-4 8-6 victory.
It's Opelka's first win in the main draw at SW19 and Wawrinka admits that he's struggling to now compete with the world's top players.
"I think before my surgery I was really consistent, finishing top five a few years in a row, playing some big tournaments, going far there," he said.
"Now it's been a bit different. But I'm really happy the way I'm playing.
"Hopefully I can keep playing well. I think I'm playing great tennis.
"Today it's a tough loss, that's for sure. But now it's just a tennis match. The season is really long. There is a lot of tennis to play. I'm excited for the rest of the year."
Simona Halep has set up a Wimbledon third round meeting with former Australian Open champion Viktoria Azarenka.
Seventh seed Halep was a three-set victor over her fellow Romanian Mihaela Buzarnescu.
While Azarenka beat Ajla Tomljanovic for the loss of just two games.
Third see Karolina Pliskova, and eighth seed Elina Svitolina were among the others moving through to round-three today.
