Janine Beckie made Olympic history as Canada earned a dramatic 2-0 win over Australia on Wednesday in the opening women's soccer match for both teams.
Beckie opened the scoring just 20 seconds into the game, an Olympic record. Canada made it stand despite playing the final 71 minutes short-handed after Shelina Zadorsky received a red card.
Beckie had a glorious chance to cement the win on a penalty kick in the 73rd minute but couldn't convert.
Canada had another solid scoring chance when Jessie Fleming came in alone and put a shot through the Australian netminder's legs that was going in before being cleared from harm's way by an Australian.
But Sinclair clinched the victory by scoring in the 80th minute, the 163rd goal of her international career.
Canada wasted no time opening the scoring in an eventful first half. Sinclair intercepted a pass deep in Australia's zone. She then found Beckie in front, who re-directed the ball into the goal.
But the Canadians lost Zadorsky to a red card in the 19th minute, leaving Canada a player short for the remainder of the contest to nurse the slim lead.
Zadorsky grabbed an Australian attacker by the shoulder, forcing her down. She didn't argue the call as the official issued the red card.
Not only was Zadorsky banished from the game but she faced a suspension for Canada's second preliminary round game versus Zimbabwe on Saturday.
Later in the half, Canadian goalkeeper Stephanie Labbe was slow to get up but after receiving treatment to her leg remained in the contest.
