Katie Boulter reached the Progress Tour Women's Championships semi-finals with a dominant 6-1 6-3 victory against fellow Briton Emily Arbuthnott.
Boulter, who beat Alice Gillan on Tuesday, will play British number seven Jodie-Anna Burrage in her final round-robin match before Friday's semi-final.
The 23-year-old is the favourite to win the domestic tournament at Roehampton's National Tennis Centre.
"I was relaxed today," Boulter told BBC Sport.
"I came out strong. I was very happy with the way I was playing."
After time out with injury, former British number two Boulter has dropped to 13th in the national rankings and was playing her second match in 19 weeks.
