Jennifer Jones carried the Canadian women's curling team to the semifinals with a 5-3 victory over the host Russians at the 2014 Sochi Olympics.
This win keeps Canada undefeated at 7-0, and could just about wrap up first place in the round-robin stage.
The Russian women, led by Anna Sidorova, fell to 3-4, fifth in the standings as of the completion of the match.
After stealing the deuce in the fifth end to go up 5-2, Jones played a relentless game. She didn't surrender a single Russian point over the following three ends, which were all blank.
It wasn't until the ninth end, where Sidorova was finally able to break through and take advantage of the last shot hammer, earning a single.
The Russians were forced to concede in the 10th end after Jones ran them out of rocks.
Earlier on Saturday, Canada beat Japan 8-6.
