Just a year after hosting the U.S. Open, the Olympic Club in San Francisco was selected Monday to host the U.S. Golf Association's inaugural men's amateur four-ball championship in 2015. Bandon Dunes Golf Resort on the Oregon coast will hold the first women's event that spring.

It's the first time since the State Team Championships in 1995 that the USGA has introduced a new championship. Adding these two tournaments means the end of two others: the U.S. Amateur Public Links, which dates to 1922, and the U.S. Women's Amateur Public Links.

The opening of the Earthquakes' new stadium has been delayed until the second half of the 2014 season because of excavation issues at the construction site, the team announced.

As a result, the Earthquakes will play eight home games at Buck Shaw Stadium, one at Stanford and nine in the new building, which will seat 18,000. The opening date is unknown because Major League Soccer's schedule is in flux because of the 2014 World Cup in Brazil.

Cal alum Dana Vollmer earned a bronze medal in the women's 100-meter butterfly -- the event she won at the London Games last year -- at the swimming world championships in Barcelona, Spain.

Vollmer, who trains in Berkeley, got sick just before the meet began this week. She called it "a sinus, head, lungs thing." Swedish teenager Sarah Sjostrom regained her butterfly world title with a victory in 56.53 seconds. Australia's Alicia Coutts was second at 0.44 back while Vollmer, the world record-holder, was 0.71 behind.

Former Cal star Nathan Adrian also is sick, according to men's coach Bob Bowman, but Adrian helped the Americans take the lead on the opening leg of the 400-meter relay Sunday night. France won the race with the United States earning a silver medal.

Former Stanford star Eugene Godsoe won a silver medal in the 50 butterfly, finishing .04 of a second behind Cesar Cielo of Brazil with a time of 23.05 seconds.

Former Cal star Caitlin Leverenz finished fifth in the women's 200 individual medley.
