1. Ertz is back home at position she played at Santa Clara.
Ertz played as a midfielder for nearby Santa Clara and that's the position she's been playing since August for the USA after starting at center back at the 2015 Women's World Cup and 2016 Olympics.
She showed why she is one of the most feared players in the air, flicking on Megan Rapinoe's corner kick with her head at the near post to give the USA a 1-0 win.
In the seven games Ertz started in midfield since August, she recorded six goals and the year second on the U.S. team in scoring.
2. Morgan finishes with eight goals in her last eight games.
Canadian Nichelle Prince blew past the left side of the U.S. backline to find Houston Dash teammate Janine Beckie for the equalizer in the 50th minute, but the USA regained the lead seven minutes later.
Christen Press stole the ball from UCLA star Jessie Fleming and fed Alex Morgan, who put the USA back ahead with her eighth goal of the season -- all in her last eight games -- and 80th of her career.
With Canada's John Herdman bringing on four teenagers, three of them eligible for the 2018 U-17 World Cup for the last half hour, the USA repeatedly broke down the Canadian defense to get an insurance goal from Lloyd, the 98th goal of her career but just the second of the year, with an easy tap-in in the 80th minute.
3. Rapinoe completes big comeback year.
A year ago, it would have been hard to imagine Rapinoe, then still recovering from her third ACL knee injury that almost kept her out of the Rio Olympics, would have the year she has had in 2017: three goals and a team-high five assists for the USA and 12 goals for the Seattle Reign in the NWSL.
Rapinoe assisted on Ertz's goal, beat her defender to play the ball in that Morgan flicked on to Lloyd for the third goal and had two long-range shots saved by Canada keeper Stephanie Labbe.
There is still no one on the U.S. team who can take set pieces and serve balls into the area like the 32-year-old Rapinoe. With youngsters Crystal Dunn, Mallory Pugh and Rose Lavelle and Tobin Heath all out for the Canada series, Rapinoe showed off her value as the main threat on the wings.
Trivia. The USA is 48-3-7 against Canada and has not lost since 2001, a span of 33 games.
