Toronto FC defender Marvell Wynne was named Sunday to the United States national soccer team ahead of the Americans' crucial World Cup qualifying contest against Mexico.

Wynne and the U.S. will host the Mexicans in the opening match of the final round of the CONCACAF qualifiers on Wednesday in Columbus, Ohio.

Wynne's only previous two appearances for the U.S. came at the 2007 Copa America tournament in Venezuela and last month in an exhibition game against Sweden. He was also a starter for the U.S. at last summer's Olympic soccer tournament in Beijing.

Wynne was one of eight Major League Soccer players included on the 20-man roster, joining the likes of Los Angles Galaxy forward Landon Donovan (currently on loan at German club Bayern Munich), Chivas USA midfielder Sacha Kljestan and Columbus Crew defender Frankie Hejduk.

The U.S. and Mexico, along with Costa Rica, El Salvador, Honduras, Mexico, and Trinidad and Tobago, are competing in the final round of the CONCACAF qualifiers, a 10-game round robin. The top three teams automatically advance to the 2010 FIFA World Cup in South Africa.

The fourth-place team will compete in a two-game playoff against the fifth-place finisher in South American qualifying.
