Top seed Johanna Konta overcame a second-set wobble against Australia’s Ashleigh Barty to claim a 6-3 7-5 victory and reach the semi-finals of the Nottingham Open on Friday.
Cheered on by the home crowd the world number eight eased through the first set but fell a break behind in the second before upping her game to avoid a deciding set.
Konta won a round at Wimbledon for the first time last year after four opening round defeats but after her rapid rise up the rankings, including the title in Miami this year, she will be expecting a deep run at the All England Club.
She will continue to sharpen her game with a Saturday semi-final in Nottingham against Magdalena Rybarikova who beat American qualifier Kristie Ahn.
Croatia’s Donna Vekic, a former finalist at the Birmingham grasscourt event, also reached the last four with a 6-2 6-3 defeat of Greek player Maria Sakkari.
