Antonio Vivaldi and Enza Rossano of Italy came through with a powerful 65.28% game in the second final session to win the J.M. Weston Mixed Pairs yesterday. This pair has won many titles in Italy and in Europe.

They needed that big game - Claude Blouquit and Marc Bompis of France came roaring through the final with a super 68.64% game to take the silver medal and just miss the gold. Vivaldi and Rosano averaged 64.07% over the final two sessions, while Blouquit and Bompis had 63.96%

The winners led after Saturday's qualifying sessions. They fell to fourth place in the first final session, but they still had plenty left to pull back and win the crown. The two pairs finished well ahead of the bronze medalists, Jens and Sabine Auken of Denmark. They had 62.39% for the day. Another French pair - world champion Paul Chemla and Catherine D'Ovidio, were fourth, followed by the German pairing of Andrea Rauscheid and Nedja Buchlev.

The highest ranking non-European pair was Martha and Ralph Katz of the United States, who were sixth. European pairs took 10 of the top 11 placings. The first Far East pair was Michael Courtney and M. Courtney of Australia.
