PRAGUE (Reuters) - Roger Federer and Rafael Nadal took care of business in their singles matches before teaming up in an eagerly anticipated doubles pairing to extend Europe's lead over players from the rest of the world in the inaugural Laver Cup on Saturday.
The new team tennis event, kicking off in Prague and moving to the United States next year, was a first chance for the world's top two players to play competitively side by side.
