The ponies aren't running only at the Sonoma County Fair.
Saturday afternoon, polo horses from across the Bay Area displayed their speed, agility and beauty at a benefit competition at the Wine Country Polo Club on the edge of Oakmont.
The occasion: the first Stick & Ball Polo Cup, a sunbathed Valley of the Moon festival of food, wine and equestrian sportsmanship that raised money for the Breast Cancer Emergency Fund.
"I have four friends with breast cancer right now," said the tournament's founder, Elizabeth Goodwin Welborn. They were her inspiration to bring the benefit event to the polo fields created by Henry Trione, an aficionado of the sport and one of Sonoma County's most generous benefactors.
More than 60 guests thrilled at the fast-paced play, tasted wines from Argentina -- the center of the polo world -- and savored an Argentine asado meal.
Among the day's special guests was player Toto Socas of Argentina, nephew of one of the game's brightest stars, Adolfo Cambioso.
In addition to coordinating the event, Welborn competed as a member of the Wine Country Polo Club and raised additional dollars for the Breast Cancer Emergency Fund through sales of items from her clothing line, Stick & Ball.
Also on the sidelines, artist Teresa Onoda displayed a selection of her landscapes and offered to make a contribution to the cancer fund with each sale.
