Juergen Klinsmann gets things started at Stanford Stadium. (By Tony Avelar — Associated Press)

Greetings from the Bay Area.

With the World Cup four weeks away, the U.S. squad has begun to gather at Stanford for two weeks of work.

[My formal story from Day 1 of training camp.]

Not everyone was on the field right away:

Graham Zusi and Matt Besler played 90 apiece Wednesday in Sporting Kansas City’s 2-1 home loss to Philadelphia. “We played like crap,” Besler said.

Maurice Edu did not play for the Union after suffering concussion symptoms and flew straight to California. Because of the head issues, however, the medical staff limited his activities Wednesday.

Michael Bradley went 120 minutes for Toronto FC in a Canadian Championship semifinal with Vancouver. (TFC advanced on penalty kicks after a 3-3 draw through two matches and extra time to advance to the final against Montreal.)

Omar Gonzalez, sidelined by a knee injury for more than a week, underwent treatment here with the aim of beginning workouts at the end of the week.

Aron Johannsson has remained with AZ Alkmaar for the Eredivisie’s Europa League playoff with Groningen, Thursday at home and Sunday away.

Jermaine Jones and Besiktas remain in contention for a Champions League qualifying berth heading into Saturday’s Turkish league finale against Genclerbirligi.

Tim Howard, Brad Guzan and Geoff Cameron were excused until the weekend.

Mix Diskerud was scheduled to arrive late in the day after serving in the 18 (but not playing) for Rosenborg on Monday.

*Klinsmann has scheduled an intrasquad scrimmage for Saturday. All sessions at Stanford are closed to the public. Most will also be closed to the media. The scrimmage is closed, as well. The team utilized Stanford Stadium, the 50,000-seat football venue, on Wednesday but will also access the adjacent soccer facility regularly.

*The U.S. delegation did not expect to train in oppressive weather until it arrived in Florida in a few weeks, but on the opening day of camp, the thermometer reached the mid-90s — 20 degrees above average. More of almost the same Thursday, but cooler temps are coming this weekend.

*DaMarcus Beasley, on the U.S. team’s group outlook:

“We have shown in the past, we can get out of our group, even in a tough group. And we’ve shown in the past we haven’t been able to get out of our group. So we need to get off to a good start against Ghana and then go from there.”

*Results of the Insider’s poll about Klinsmann’s decision not to invite Eddie Johnson: Of the 1,400-plus voters so far, 60 percent agreed, 40 percent disagreed. (Still time to vote!)

*While 15 MLS players were invited to U.S. camp, 16 others from around the league were named to World Cup 23- or 30-man rosters:

New York F Tim Cahill (Australia)

Toronto GK Julio Cesar (Brazil)

Toronto F Jermain Defoe (England)

Chivas USA MF Oswaldo Minda (Ecuador)

Vancouver D Steven Beitashour (Iran)

Columbus F Jairo Arrieta (Costa Rica)

Real Salt Lake F Alvaro Saborio (Costa Rica)

New England F Jerry Bengtson (Honduras)

Defoe, Minda, Arrieta and Leveron are not in the 23 at the moment

FIFA will post the 30-man lists for all 32 World Cup teams Thursday.
