The roster includes 15 players with World Cup experience, 17 who have played against Mexico before
The Americans will entertain Mexico on Friday at Columbus, Ohio, in the opening match in the "hexagonal," the six-team round robin qualifying series from the North American (CONCACAF) region. Four days later they continue qualifying by trying to claim a first-ever victory at Costa Rica.
US players have beaten Mexico 2-0 at Columbus in qualifying for the 2014, 2010, 2006 and 2002 World Cups, making "Dos a Cero" a catchphrase as the team launches its bid to reach Russia.
The roster includes 15 players with World Cup experience, 17 who have played against Mexico before and 11 of those who have done it in qualifying.
"Obviously the Mexico clash is a six-pointer to start the Hexagonal right away," Klinsmann said. "We badly want to continue the tradition of beating them in Columbus."
Among the players called up by Klinsmann was English-born 18-year-old defender Cameron Carter-Vickers, a Tottenham Hotspur developmental squad player who might get a first nod to link him to the American side after youth play on US squads.
"Having 26 players coming in gives us many different options for both games," said Klinsmann. "It allows us to evaluate certain players, like a Jermaine Jones, to see how far he has come along fitness-wise. Bringing in the likes of Cameron Carter-Vickers, Lynden Gooch and Caleb Stanko proves that the younger players are pushing through."
The Americans are 8-0 with three drawn at Columbus with 10 shutouts at the venue and a 7-0 with two drawn qualifying record there.
