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 - Seven-time champion Rafael Nadal could face top-seeded Novak Djokovic in the French Open semifinals a year after they met to decide the title.

Friday's draw for the clay-court Grand Slam tournament placed Nadal and Djokovic on the same half of the field, while Roger Federer could face David Ferrer in the other semifinal.

Federer, the owner of a record 17 major titles including the 2009 French Open, will face a qualifier in the first round - and if he wins that, he'll play a qualifier in the second round, too.
