Mexico will have to play up to six games to retain the Gold Cup in the us, starting on Sunday against El Salvador in San Diego.
After getting a goal in his American debut last weekend against Ghana, the England-born Dwyer scored in the 50th minute with a left-footed shot from 9 yards that went in off the far post.
With the goal in his U.S. debut last week, Dwyer and his spouse Sydney Leroux became the first husband-and-wife duo to each score for the USA. Mexico won the last CONCACAF in 2015, when the USA lost in the semifinals 2-1 to Jamaica.
Panama countered straight after and Miguel Camargo's right-footed shot, after cutting in from the left, forced Brad Guzan into a fingertip save in the US goal. Canada, who won the Gold Cup tournament in 2000, are undefeated in their last three friendlies, having beaten Bermuda 4-2 and Curacao 2-1, in between a 1-1 draw away to Scotland. Panama tied the Americans in the first round two years ago, then won on penalty kicks in the third-place match. It should be noted that most of the players on this roster are not "A" team guys so for so many of them to put in solid performances is very good. The Sporting Kansas City star became a citizen in March and looks like he can be a fixture on the A team. In March, after eight years of residence in the States, he gained American citizenship, finally allowing him to suit up for the US, like his wife, Sydney Leroux, has done for the USWNT 75 times.
"We didn't play well on the day", USA coach Bruce Arena said. "Anytime you get a chance to step on the field when the so-called regulars aren't here, you want to make a good impression". The Americans finish group play next Saturday against Nicaragua in Cleveland.
The United States' second match is against Martinique on July 12, with Panama facing Nicaragua on the same day. Drawing large crowds and millions of television viewers from across the region, the Gold Cup is a celebration of soccer, sportsmanship, and culture. Not recognized as a member of Federation Internationale de Football Association, the country acts as an overseas department for France, meaning that players from French Guiana can play for both France's national team and their own. He also scored against Chile past year in the Copa America at Philadelphia.
Then there's the younger crop, headlined by FC Dallas midfielder Kellyn Acosta (21) and Seattle Sounders midfielder Christian Roldan (23), who could become the faces of the US midfield once Bradley is out of the picture.
Three teams have automatically qualified for the Gold Cup since 2003, regardless of their standing in CONCACAF. Bedoya replaces Paul Arriola at wide midfield and Gonzalez took over for Matt Hedges in central defense, paired with Matt Besler.
The 2017 Gold Cup will feature four first-time hosts: Alamodome (San Antonio, Texas); FirstEnergy Stadium (Cleveland, Ohio); Levi's Stadium (Santa Clara, California); and Nissan Stadium (Nashville, Tennessee).
