SAPPORO, Japan - Russia's Anna Sidorova defeated Scotland's Eve Muirhead 7-2 in the Page playoff 3-4 game on Friday to reach the semifinal at the world women's curling championship.

Sidorova scored a deuce in the eighth end for a 5-2 lead and added two more points in the ninth for the victory at the Tsukisamu Gymnasium.

Muirhead had claimed the final playoff spot earlier in the day with a 9-4 win over China's Sijia Liu in a tiebreaker game.

Sidorova will next play the loser of Saturday's Page playoff 1-2 game between Canada's Jennifer Jones and Switzerland's Alina Patz.

Jones and Winnipeg-based teammates Kaitlyn Lawes, Dawn McEwen and Jill Officer finished the round robin in second place with a 9-2 record. Patz earned the top seed with a 10-1 mark.

The 1-2 game winner advances to Sunday's gold-medal game.
