Debbie McDonald and Brentina were a discretionary selection and were named to the Short List on June 4th . They were ranked first in the nation after the qualifying competitions for the Olympic Selection Trials. They are also ranked #2 in the World according to the FEI Rankings, and are the 2003 World Cup Champions.
Robert Dover finished first overall in the 2004 Olympic Dressage Selection Trials just completed this past Sunday in San Juan Capistrano, California. Dover won all four competitions in the Trials giving him a place on the Short List; the 2004 Games will be Dover’s sixth Olympic Team. Guenter Seidel on either Aragon or Nikolaus was second and third in each of the Trial’s competitions to finish an overall second on Aragon, and third on Nikolaus.
Lisa Wilcox currently resides in Europe where she competes. The selection procedures allow for a rider competing in Europe, and not participating in the Trials, to be selected for the Short List provided they have an average at least two percentage points higher than the fourth ranked rider/horse combination coming out of the two selection trials. According to the selection procedures, Wilcox and Peters will be required to compete head-to-head in designated pre-Olympic European competitions to vie for the fourth spot on the Olympic Dressage Team.
The team leaves next week for Europe where they will compete in Germany at Aachen, July 13 - 18 and Lingen. Leslie Morse will go to Europe to train with the other short listed riders as the U.S team. She may also compete at some of the pre-Olympic competitions if an additional invitation can be secured. Morse will be available if another horse/rider combination has to be replaced.
Olympic Dressage riders are only allowed to ride one horse per games. The Selectors and Coach Klaus Balkenhol along with Guenter Seidel, will decide which horse he will take to Athens after the competitions in Europe are completed.
