GLASGOW, Scotland — An early start to the Olympics turned into an early deficit for the U.S. women’s soccer team, which gave up two quick goals before unleashing an attack the rest of the world will find hard to stop.

Abby Wambach used her size and strength to put in a header, Alex Morgan scored twice and Carli Lloyd added another with a 25-yard rocket to help the two-time defending goal medalists rally for a 4-2 victory over France on Wednesday.

The Americans opened their London Games far from London and two days before the opening ceremony. Soccer starts its Olympics early so it has time to play a full tournament of games.

The Americans allowed more goals in the first 15 minutes than they had allowed in any game since the World Cup final loss to Japan last year. Gaetane Thiney scored in the 12th and Marie-Laure Delie added a second in the 14th, finding holes in a supposedly impenetrable defense — a potential cause for U.S. concern as the grueling tournament progresses.

But Wambach scored in the 19th, Morgan in the 32nd, Lloyd in the 56th and Morgan again in the 66th. Wambach now has 139 international goals in her pursuit of Mia Hamm’s record of 158, and 23-year-old “Baby Horse” Morgan — the second-youngest player on the team — has a remarkable 19 this year alone.

While the Americans are favored to win gold again — and even though the U.S. is now 13-0-1 all-time against France — it was hardly a surprise to see the French make it a game. The teams were level late in the second half in last year’s World Cup semifinals before the Americans finished off a 3-1 win, and France entered these Olympics on a 17-match winning streak.

The United States plays Colombia in its second group game on Saturday. France will face North Korea.

The French took the lead from a deflected long ball that ended up at the foot of Thiney, who had plenty of time and space to unleash a 22-yard shot into the upper right corner of the net, grazing the fingertips of leaping goalkeeper Hope Solo.

Two minutes later, the Americans played a dangerous game of pinball deep in their own end, failing in five separate chances to clear a corner kick. Inevitably, the ball bounced to a French player, Delie, who put an easy shot past Solo, again off the goalie’s outstretched left hand, to make it 2-0. But the Americans are arguably stronger, deeper and more diverse than they’ve ever been, and they have the firepower to overcome such a deficit — and quickly. Wambach, who has the best header in women’s football, started the comeback by nodding in Megan Rapinoe’s corner kick.

The goal awakened some of a crowd that so far had behaved as if watching a BBC documentary. Chants of “U-S-A!” began to echo in sections of Hampden Park, the 109-year-old landmark that serves as Scotland’s national stadium.

The 52,000-seat stadium was perhaps one-third full at kickoff, but the game needed to draw only a couple of thousand to surpass the all-time Scottish record for attendance at a women’s game. Organizers gave away some 30,000 tickets to schools and local clubs to keep the stands from being embarrassingly empty in a region where football is overwhelmingly a man’s game.

North Korea angered over flag flap

GLASGOW, Scotland — London Olympic organizers mistakenly displayed the South Korean flag on a jumbo screen instead of North Korea’s before a women’s soccer match Wednesday, prompting the North Koreans to refuse to take the field for nearly an hour.

The flag flap began during player introductions when a North Korean player was introduced along with a shot of the South Korean flag.

The match against Colombia was delayed for more than an hour, and organizers apologized for the error.

“If this matter couldn’t have been resolved, then I thought going on is nonsense,” coach Sin Ui Gun said through an interpreter after North Korea won 2-0. “We were angry because our players were introduced as if they were from South Korea, which may affect us very greatly as you might know.”
