SOCHI, Russia -- Winnipeg skip Jennifer Jones made Olympic history Monday, defeating South Korea 9-4 to become the first woman to go through the Olympic curling round-robin unbeaten.
Jones had to work hard against Korean skip Kim Jisun and didn't hold a lead until the seventh end.
Jones, lead Dawn McEwen, second Jill Officer and third Kaitlyn Lawes were 8-0 going into the game and had already clinched a berth in the semifinals.
Canada's Kevin Martin, who did it four years ago in Vancouver, is the only other curler to go through the Olympic round-robin undefeated.
Kim, who throws second, finished the tournament at 3-6.
