What happened: The U.S. men's national team thanked Seattle Mariners fans for their "unbelievable energy and support" after being welcomed at T-Mobile Park, capping the appearance with a nod to the Fourth of July: "Doesn't get much more American than this." The stop is part of the Mariners' welcome of the USMNT as World Cup buildup rolls on.

Why it matters: A packed big-league ballpark embracing the national team on Independence Day is exactly the kind of crossover moment U.S. Soccer wants as it builds momentum on home soil. For the Mariners, the visit adds a marquee touch to a holiday homestand with the club riding a three-game winning streak.

What to watch: The Mariners host Toronto tonight at T-Mobile Park, while the USMNT continues its World Cup preparations on home soil.
