France led Spain 1-0 in the Davis Cup semifinals Friday, with the second singles match suspended because of darkness. Paul-Henri Mathieu upset sixth-ranked Carlos Moya 6-3, 3-6, 2-6, 6-3, 6-3 in 4 1/2 hours to give France the early lead in the best-of-five series. ``I think he played a great game. ... It was a match of ups and downs and in the end I was a little tired,'' Moya said.
