BANGKOK — On June 11, 2015, at the World Cup, the Thai women’s soccer team defeated the Ivory Coast squad, 3-2. It was the Southeast Asian nation’s debut at the tournament, and the victory was as unexpected as it was thrilling.

Four years later to the day, the Thai women made history again, victims of the most lopsided thrashing in World Cup history, losing to the Americans, 13-0.

But far from bemoaning the rout, which took place in the early morning hours in Bangkok when the streets were dark but the pavements still pulsing with tropical heat, Tanatpong Kongsai was happy that the squad was representing Thailand in its second consecutive World Cup.

“I am not embarrassed at all,” said Mr. Tanatpong, a longtime soccer fan. “The Thai national anthem was heard all over the stadium. The women’s team never disappoints Thais.”
