British number two Heather Watson continued to build up to the return of the professional tour with another fine win at the Battle of the Brits.
Watson, 28, won her fourth singles match of the week with a ruthless 6-0 6-1 victory over Maia Lumsden.
It enabled the Union Jacks to cut the gap on the British Bulldogs to 33-32 at the unique team event in Roehampton.
British men's number one Dan Evans, playing for the Jacks, takes on Kyle Edmund later on Friday.
The Union Jacks trailed 31-25 going into day five before singles wins for Watson, Jodie Burrage and Naomi Broady - plus victory for Jamie Murray and Lloyd Glasspool in the men's doubles - hauled them within a point.
