Mouat’s rink have an excellent record against Brad Jacobs’ team, and beat them in the last four of the worlds last spring.
But the Canadians knew they could improve their own chances – and inflict a little revenge – and they started strongly, opening a 3-1 lead after three ends.
The British team are considered the world’s best, though, and righted themselves. Capitalising on a slight drop off by their opponents, they took two themselves in the fourth and another two in the six to lead with four to play.
However, the clank of granite went against them in the seventh, an unfortunate bounce leaving Canada the chance of three, which they gladly took.
Mouat and his team needed to respond. They couldn’t. Instead, they gave up a steal to leave themselves with a three-point deficit with two ends to play.
It was a deficit that they could not overcome. And now, their aspirations of upgrading their silver medal from Beijing are no longer in their own hands.
GB’s women are also in a perilous position, and also must beat the United States on Wednesday (08:05), as well as Japan later in the day (18:05) and Italy on Thursday (13:05) if they are to scrape into the last four.
