Here's how the USA did it ...
1. USA doesn't mess around.
Early goals put the USA in commanding positions in all five games at the Concacaf Women's Championship. It took all of 110 seconds for the Americans get on the board against Canada. And like so often, they made their opponent pay for not playing out of danger.
Lindsey Horan beat two defenders on the left side and played a curling ball that center back Shelina Zadorsky cleared right to Rose Lavelle just outside the area. The midfielder curled her left-footed shot inside the far post for the early lead.
USA's opening goals:
MEX (6-0): Megan Rapinoe 3rd minute.
PAN (5-0): Sam Mewis 5th minute.
TRI (7-0): Alex Morgan 9th minute.
JAM (6-0): Tobin Heath 2nd minute.
CAN (2-0): Rose Lavelle 2nd minute.
2. Horan for Ballon d'Or?
Since the late summer, the USA has gone from strength to strength, winning the Tournament of Nations in which it faced Japan, Australia and Brazil, all teams that will be at the 2019 Women's World Cup, and sweeping all five games in Concacaf qualifying to improve its 2018 record to 16-0-2.
No player has been bigger for the USA than Horan, who also set up Alex Morgan for the second goal in the 88th minute with a delicate pass to the near post.
Morgan won the Golden Boot as the tournament's high scorer with seven goals and Julie Ertz won the Golden Ball as the tournament's best player but Horan was the difference maker for the USA throughout the tournament, beginning with the opening game against Mexico when she set up the first two goals.
Horan, the 2018 NWSL MVP, is one of two Americans nominated for the new Women's Ballon d'Or. She might not yet have the name recognition of Brazilian Marta or German Dzsenifer Marozsan or even Megan Rapinoe, the other American on the 15-year short list, but no other player has had as good a year as the 24-year-old Horan, who skipped college to sign with Paris St. Germain and returned home in 2016 to join the Portland Thorns.
3. Yes, Canada, there is a gap.
The gap between the USA and its first four opponents at the Concacaf Women's Championship was obvious. It was never tested en route to four easy wins: 6-0, 5-0, 7-0 and 6-0.
The final against Canada was a little different. The final was a one-goal game until the 88th minute when Morgan scored a goal that should have been called off for offside. Canada's physical style took its toll on the USA, which struggled to put the game away. But Canada finished with as many yellow cards as it did shots with four each.
Asked what it would take to close the gap between the USA and Canada in women's soccer, Canada's Danish coach, Kenneth Heiner-Moller, insisted there's no gap.
The record doesn't back that up. The win extended the USA's unbeaten streak against Canada to 34 games, dating back to 2001 when the USA took a second team to the Algarve Cup and lost to Canada, 3-0.
Trivia. Canada became the eighth World Cup-bound team the USA has beaten in 2018 along with Germany, England, China, Japan, Brazil, Chile and Jamaica, which became the first Caribbean team to ever qualify when it won the third-place game in a shootout over Panama.
