Jersey's Karina Bisson is still in line to make the play-offs at the World Champion of Champions bowls.
But Bisson has slipped from the top of her group despite beating South African Cheryl Mostert 2-10, 10-2, 4-3 and Singapore's Shermeen Lim 14-4, 11-3.
New Zealand's world number one Jo Edwards is level on points with Bisson but leads the group with a better shot difference having played a game less.
Bisson faces Edwards in her final group match in Hong Kong on Friday.
The group winner qualifies for the semi-finals automatically while the second and third-placed bowlers face each other in a play-off for the second semi-final spot against their counterparts from the other group.
