U.S. national team coach Jurgen Klinsmann invited three members of the Earthquakes to a training camp that opens Monday as the Americans begin preparation to qualify for the 2014 World Cup in Brazil.

The Earthquakes announced Sunday that forward Chris Wondolowski and fullbacks Steven Beitashour and Justin Morrow will join the winter training camp at the National Training Center in Carson. The camp ends with a friendly against Canada on Jan. 29 in Houston, after which the U.S. roster will be set for the upcoming CONCACAF qualifying tournament.

The final qualifying round for the World Cup begins Feb. 6 at Honduras.

The Americans are trying to earn one of three World Cup spots in a 10-game round robin tournament against Costa Rica, Honduras, Jamaica, Mexico and Panama. The fourth-place finisher also could advance by winning a two-game playoff against the winner of the Oceania region.

Whereas Wondolowski was expected to be invited after leading MLS in scoring three consecutive seasons, the Quakes defenders have been something of a surprise. Beitashour (30th overall) and Morrow (28th) were low draft picks in 2010 who became regulars last season.

Wondolowski, 29, got his first call-up at any level two years ago with the senior national team. The MLS's reigning most valuable player has yet to appear in a game other than a friendly. He will make his third consecutive January camp appearance.

Los Angeles Galaxy defender Omar Gonzalez will return to the U.S. team after a two-year absence, but Landon Donovan was left off the camp roster while he decides whether he wants to keep playing.
