The national team is taking its preparation seriously as five of the 10 teams the U.S. will face are ranked in the top 10 in the world.
Lavelle, who missed the majority of 2017 with a hamstring injury, said her two goals Wednesday helped her gain confidence.
The victory over Trinidad and Tabago extended the USWNT's winning streak to 24 games.
Coach Ellis changed the team's lineup from the first game with nine adjustments, keeping only Julie Ertz and Abby Dahlkemper as starters.
Carli Lloyd led the U.S. with three goals in the team's victory over Panama as she scored her 105th goal for the USWNT.
Alex Morgan had a strong night with two goals as she edges closer to reaching the 100-goal milestone.
Morgan gave the U.S. two goals — one in the 56th minute and another in the 79th — and she's now eight goals away from reaching 100.
Despite the team's recent success, the players and coaches know they're still going to have to work hard to make it to the World Cup.
