Rafael Nadal shrugged off his disappointment and fatigue from losing the U.S. Open final to rout Richard Gasquet 6-3, 6-0, 6-1 Friday and give Spain a 1-0 lead over France in their Davis Cup semifinal. Nadal overcame the loss Monday to Novak Djokovic in New York on his favored outdoor clay surface in hot conditions at Cordoba’s bullring.
