Not one MLS team (the Galaxy), not two (Chivas USA), not three (New York Red Bulls), but four (San Jose Earthquakes) are in camp at Carson’s Home Depot Center.

Former Galaxy Coach Frank Yallop and his Earthquakes (sounds like an excellent name for a polka band, doesn’t it?) play Feb. 22 and Feb. 24 against the Columbus Crew and D.C.United respectively in San Luis Obispo, incidentally. Ticket details are here.

The Galaxy listed 35 players on its pre-season camp roster including EPL veteran Celestine Babayaro, whose signing was (finally) confirmed today by GM Alexi Lalas. Babayaro is in town, but awaiting a work visa.

And, yes, Beckham was in camp enduring Super Bowl-related questions (I kid you not) from television media types.

Players listed as on trial with the Galaxy include: Liberian international Prince Daye and Temple High graduate Bryan Jordan.

The Galaxy will endure two training seassions a day under new Coach Ruud Gullit who players already know will be a far harder taskmaster than Yallop.

Still, players expect a more stable environment than last year’s circus.

“You never knew who was going to be in the locker next to you,” said midfielder Kyle Martino, fully recovered from the hernia operation he had in the off-season.

Chivas USA listed 38 players and likewise confirmed the long-anticipated signing of Swiss international Raphael Wicky. He wasn’t speaking to the media today; Chivas has set a 9 a.m. Tuesday press conference to introduce him.

Other notables on trial with Chivas USA include Mike Munoz, who played a handful of minutes for Chivas USA during their inaugural season and whose girlfriend waged a media campaign to get the team to resign him; Fontana resident Chukwudi Chijindu and 2002 Japanese World Cup veteran Takayuki Suzuki

The complete MLS schedule is set for release Thursday, by the way.

I’ll have more on the opening day of camp in Tuesday’s column.

Finally, U.S. Soccer confirmed today the opening U.S. World Cup qualifier is set for Home Depot Center June 15 against either Barbados or the Dominican Republic.

The (edited) press release:

Kickoff for the first U.S. match of the 2010 qualifying campaign is set for 2 p.m. PT, with broadcast details still to be finalized. The U.S. will face the winner of the first round series between Barbados and Dominica, who will meet on Feb. 6 in Dominica and March 26 in Barbados.

We are very much looking forward to beginning the process of qualifying for the 2010 World Cup, said U.S. head coach Bob Bradley. We have been preparing for more than a year, and selecting a venue for the match really gives us a target for everyone to focus on for the next few months. The Home Depot Center has been a great host for the national team, and we are hoping to continue our run of good results there.

The June 15 match represents the USAs first World Cup qualifier played in Carson. The U.S. boasts an unbeaten 5-0-1 record at the HDC, including two victories during the group stage of their 2007 Gold Cup championship-winning run last year. In their opening match of 2008, goals by Eddie Robinson and Landon Donovan lifted the USA to a 2-0 win against Sweden. It is also the first World Cup qualifying match that the U.S. MNT has played in Southern California since a 1-1 draw with Trinidad & Tobago on May 13, 1989 in Torrance.

The U.S. has never faced Dominica and only played Barbados twice in the Mens National Teams 91-year history. The only meetings between the U.S. and Barbados took place in the Semifinal Round of 2002 World Cup qualifying in a group that also included Guatemala and Costa Rica. The U.S. dominated both matches, winning 7-0 on Aug. 16, 2000, in Foxborough, Mass., before cruising to a 4-0 victory in the final group match on Nov. 15, a win that booked the USAs passage to the final phase.

Should the U.S. advance, the semifinal round will take place from August to November, with the teams divided into three groups of four teams each. Playing a six-game round robin format, the top two finishers from each group will advance to the final six-team group that will play in 2009. The U.S. could potentially face Guatemala, Trinidad & Tobago and Cuba should each country advance out of their early-round series.

CONCACAF World Cup qualifying began Sunday, by the way.
