Dan Evans through, Harriet Dart eliminated in Nottingham Open

Men's top seed Dan Evans has been left as Great Britain's only hope in the Nottingham Open singles event after a tough day for the home favourites.

Evans's strong start to the grass-court season continued as he advanced to the semi-finals courtesy of a 6-4 6-4 victory over Marc-Andrea Huesler of Switzerland.

GB started the day with three representatives in the men's quarter-finals, but only Evans will contest the last four following defeats for Liam Broady and Ryan Peniston.

Peniston was swept aside 3-6 4-6 by Australia's Alexei Popyrin, while Broady lost 6-7 6-1 4-6 to the USA's Jack Sock, who faces Evans in the semi-finals.

Meanwhile, Harriet Dart could not back up her first WTA Tour quarter-final appearance with another win as she went down in three sets to Alison Riske.

Dart began the contest on the front foot before her serves let her down - posting just a 48% success rate on first serves and losing 6-4 2-6 1-6 to the American.

Top seed Maria Sakkari also lost in fiery fashion to Brazil's Beatriz Haddad Maia 4-6 6-4 3-6, during which she had some choice words to the umpire about her opponent's antics.

Haddad Maia faces Tereza Martincova for a spot in the women's final, while Riske faces a semi-final showdown with Viktorija Golubic.
