Kerri Einarson picks up bounce-back victory over Turkey at women's curling worlds

Canada's Kerri Einarson improved to 2-1 at the women's world curling championship Sunday with an 8-4 win over Turkey in Prince George, B.C.

The host country was to meet defending champion Silvana Tirinzoni of Switzerland (2-0) in the evening draw.

Einarson's foursome out of the Gimli Curling Club in Manitoba scored three points in the fourth and sixth ends en route to the victory over Turkey's Dilsat Yildiz, who conceded after the seventh end.

The same problem occurred in Olympic curling last month in Beijing, although the World Curling Federation stones used at the CN Centre are a different set.

Sensors in each stone's handle determine whether the rock is released before touching the hog-line. A green light indicates a legal delivery, while a red light indicates a violation and the stone gets pulled.

For the rest of the women's championship, it will be up to players to call any violations as was the case midway through men's and women's team curling in Beijing.
