ATLANTA — The United States had everything on its side. History. A raucous home crowd. And, supposedly, the better team. None of it prevented Jamaica from handing the Americans their biggest upset defeat. The Reggae Boyz scored first-half goals, one off a blunder by goalkeeper Brad Guzan, and held on for a 2-1 victory in the CONCACAF Gold Cup semifinals Wednesday night. Instead of heading on to a berth in Sunday's title game at Philadelphia, the American will play for third place. "Obviously the team is disappointed. The fans are disappointed," U.S. coach Jurgen Klinsmann said after the Americans lost to Jamaica for only the second time in 23 meetings. "We wanted to play in the big final."Darren Mattocks, who plays for the Vancouver Whitecaps in Major League Soccer, put Jamaica ahead with a 31st-minute header directly off a throw-in. The Houston Dynamo's Giles Barnes followed five minutes later with a goal on an 18-yard free kick after Guzan was caught outside the penalty area on a routine throw. Other than those two set plays, the Americans largely dominated. They had a 10-3 edge in shots on goal, including eight in the second half, as they furiously charged at Jamaican goalkeeper Ryan Thompson, who played for the University of Tampa and the Rowdies. Thompson turned aside every shot but Michael Bradley's goal in the 48th minute. "My phone hasn't stopped, as you can imagine," Barnes said. "Back in Jamaica, there's got to be a party going on." A team ranked 76th in the world became the first Caribbean nation to reach a Gold Cup final. The Jamaicans want more, said their German coach, Winfried Schaefer. "We have one more match to play," he said. "Bob Marley is for after the match." The 34th-ranked Americans, who had played in five straight Gold Cup finals and were the defending champs, must meet the Gold Cup winner in a playoff for the North and Central American and Caribbean berth in the 2017 Confederations Cup. The last time the United States lost to a Caribbean team at home during a World Cup qualifying segment was a 1-0 defeat to Haiti in 1969."David beat Goliath," Schaefer said.In their first game in Atlanta in 38 years, the Americans had most of the chances but kept sending good looks wide or over the net. "You have no divine right to be in the final,'' Bradley said. "We certainly didn't think that. We knew from the get-go this was going to be an extremely difficult tournament."Jamaica jumped ahead when Kemar Lawrence's long throw-in was delivered into the penalty area. Mattocks leaped for a header that caught the underside of the crossbar and dropped beyond the goal line. Minutes later, on a routine throw downfield from the edge of the penalty area, Guzan's right arm went over the line when he let go of the ball. That gave Jamaica a free kick and Barnes hooked a shot over the defensive wall and into the right side of net. "It's a call you don't see very often,'' Bradley said. "It's a call I wouldn't be making if I was a referee. But I'm not a referee." Howard set to return: Goalkeeper Tim Howard is ready to make himself available for the U.S. national team after taking a break since the 2014 World Cup. Howard, 36, who plays for Everton in the English Premier League, was allowed a sabbatical from international soccer in August and is targeting selection for the United States' friendly match against Peru on Sept. 4.
