MOORE, Okla. - After living nearly 20 years in their one-story brick home, Sherry and Larry Wells finally won the lottery - for a state rebate on a home storm shelter, that is.

PARIS - Perhaps not surprisingly, the first three questions posed to Roger Federer at his pre-French Open news conference Friday concerned rival and nemesis Rafael Nadal.

The third was about the difficulties of making a successful return from injury, the way Nadal has, reaching the final at all eight tournaments he's played in 2013 after going more than half a year between matches.

Nadal, who's dealt with recurring knee problems, will be back in Grand Slam action after nearly a year's absence from the four most important tournaments in tennis.
