For the first time in more than a decade, teams returned to Morven Park’s grass polo field to compete in the revived Ambassadors’ Cup Invitational, while a crowd of well-dressed spectators competed for their own prizes.

The match celebrated the 50th anniversary of the Chief of Protocol trophy, originally created by the U.S. State Department as a tool of international diplomacy, and served to kick off the weekly Polo in the Park series that begins July 9 and continues Saturday nights through the summer. 

The event enjoyed clear, sunny skies, but strong winds played havoc with the elaborate hats displayed by spectators. Christina Shu, sporting a butterfly-theme hat, took home the top prize in that category. For the men, it was Bernard Mustafa in a seersucker suit who won the dapper dresser award. 

“It was a beautiful day at Morven Park to welcome everyone to the Ambassadors’ Cup Invitational Polo Match. It had been 12 years since our last match was played on the grass field, so we were excited to bring this event back to the community,” Morven Park Executive Director Stacey Metcalfe said. 

Included in the day of tailgating and romping polo ponies was a visit by the Loudoun Hunt hounds, a trick riding performance by KJM Enterprises, and carriage driving demonstrations by the Piedmont Carriage Club and the USEF Developing Driving team.
