His wife, Catherine, awarded the trophy cup to William and his three teammates after the royal couple exchanged congratulatory kisses on both cheeks. She also gave Tiffany gifts to all 12 polo players who played on the three teams participating in the six chukkars, or six periods, of Saturday's play.  Before the game, the prince declared he and wife Catherine arrived at "one of the most beautiful polo grounds anywhere in the world" to raise money for charity and compete.
