LONDON (Reuters) - Rafa Nadal might have been condemned to a lowly 10th seeding at Wimbledon but he remains a floater everyone will want to avoid after getting his campaign off to an impressive start with a straight-sets dismissal of Thomaz Bellucci on Tuesday.

The twice champion, who has slipped down the sport’s pecking order after 18 months of injury and below-par performances, showed glimpses of his power and determination in a 6-4 6-2 6-4 win over Brazil's Bellucci on a sun-drenched Number One Court.
