With the ATP and WTA Tours suspended since March and resuming this month, the Battle of the Brits allowed the players to build up fitness and sharpness in a competitive environment.
Former world number one Andy Murray only played in the doubles as he continued to build up his fitness after struggling with pelvic and shin injuries this year.
The 33-year-old Scot is planning to play the Cincinnati Masters and the US Open, which are being held in a two-tournament safety bubble in New York when the ATP Tour on 22 August.
“My game is in a decent place but it is tough to comment about the body until I’m out there playing competitive singles matches, that’s where it will really get tested,” Murray said.
“I feel I’ve played pretty well in the matches and the basics of the game, serving and returning, have been good.”
Britain’s leading women’s players, Konta and Watson, are also planning to return to the professional tour in the States at the WTA tournament in Lexington next week.
Konta, ranked 14th in the world, had not played since the tour was suspended in March and, after losing her opening match to Jodie Burrage, improved as the week wore on at the National Tennis Centre.
But the 29-year-old, who has been managing a knee tendon problem this year, did not play at all on Sunday.
Watson, ranked 50th in the world, maintained her 100% winning record in the singles by beating Beth Grey for a fifth victory.
Evans says his game is in a “good spot” before the restart of the tour, while British men’s number two Edmund says he is raring to return to professional action after winning his fourth singles matches in a row.
