HOUSTON - Ashley Lawrence had a hat trick and 16-year-old Deanne Rose had two goals as Canada's women's soccer team cruised to a 5-0 victory over Guyana in its first game of the CONCACAF women's Olympic qualifying tournament.

Rose scored Canada's first and third goals in the first half while Lawrence added one in the first half and two more early in the second as Canada, ranked No. 11 in the world, outclassed No. 89 Guyana.

Canada sits in first place in Group B tied with Trinidad and Tobago, who beat Guatemala 2-1 earlier in the evening. Canada holds the advantage due to a superior goal difference.

Making just her second start and playing in just her fourth game at the senior level, Rose provided the breakthrough after Guyana sat back in numbers allowing Canada to attack in wave after wave.

In the 26th minute, Rose deflected a Sophie Schmidt header to finally break the deadlock.

The goal came on Canada's first corner kick of the night. The Canadians got their second in the same fashion just two minutes later.

Forward Christine Sinclair, so often the scorer for Canada, was the provider of the corner kick on the first two goals.

Sinclair lofted in a high corner from the right side and Lawrence got her head to the ball. The ball just barely crossed the line before being cleared.

Rose gave Canada a third goal in the 39th minute when she used a burst of pace to get past a defender and then placed her shot into the low corner to the right of Guyana goalkeeper Chante Sandiford.

Lawrence got her last two goals within the first three minutes of the second half.

First, she headed in a cross that Rose delivered from the right in the 46th minute and then two minutes later, hit a strong right-footed shot from the middle of the penalty area after Sinclair put the ball right into her path.
