Two wins for Scott saw her jump above previous leader Nor Hashimah Ismail of Malaysia and into first place on 30 points.

The Australian claimed a 10-6, 11-5 win over Hajah Salleh of Brunei in her opening contest before picking up her second win of the day with a 23-1, 11-4 success against Botswana's Obakeng Gaborutwe.

Guernsey’s Lucy Beere also finished on 30 points but took second in the standings after having fewer shots, which is bowls nearest the jack.

Beere first defeated Hilda Tam of Macau 15-3, 15-6 before beating Ismail 8-7, 9-9 to go above the Malaysian into second place at the Australian venue.

Ismail finished in third place on 27 points.

New Zealand's Jo Edwards finished top of the women's section two standings despite losing one of her matches today.

Edwards, the Glasgow 2014 Commonwealth Games gold medallist, beat Loa Babona of Papua New Guinea 17-3, 9-7 but went on to lose her second match, against Tammy Tham of Singapore, 9-6, 2-12, 3-2.

Scotland's Lesley Doig finished second in the rankings with Ronalyn Greenlees of The Philippines finishing third.

Scotland's Ronnie Duncan still leads section one of the men's competition with just one round of matches left to play. 

The Scot defeated Phil Jones of Norfolk Island 13-5, 13-4 today to move onto 33 points.

The defending champion, James Henry of Australia, lies in second place on 30 points after he got the better of Hirendra Bhartu of Canada 12-2, 4-11, 3-2.

South Africa's Pierre Breitenbach retained the lead in section two of the men's event with another victory.

Breitenbach got the better of Scott Roberts of the United States, 11-6, 7-7.

Both section winners in the men's and women's competitions earn a direct place in the semi-finals.

The second and third-placed bowlers from both sections will then play against each other in a bid to fill the other two semi-final places.
