Fabian Johnson earns start at right back for US.

SAN FRANCISCO (AP) Fabian Johnson is starting at right back for the United States against Azerbaijan at Candlestick Park in the first of three World Cup warmups for the Americans.

Matt Besler and Geoff Cameron are the central defenders Wednesday night. DaMarcus Beasley, looking to become the first American to appear in four World Cups, is at left back.

Johnson started three games at left back last year but just once on the right - in the clinching World Cup qualifier against Mexico in September.

The Americans are opening in the 4-4-2 formation they used in the first half of last month's exhibition against Mexico. Michael Bradley is at the top of the midfield diamond, with Jermaine Jones deep, Graham Zusi on the right and Alejandro Bedoya the left. Jozy Altidore and Clint Dempsey are the forwards.
