While rain delayed play on all other courts Wednesday, five-time champion Venus Williams and 40-year-old Japanese veteran Kimiko Date-Krumm were playing in the main stadium.

The winner of the early match on Centre Court will reach the third round, but there are still 17 first-round matches that have not finished or even begun at the All England Club.

Later Wednesday, defending champion Rafael Nadal was to play Ryan Sweeting of the United States on Centre Court.

Three-time Wimbledon runner-up Andy Roddick was scheduled to play in the late match against Victor Hanescu of Romania.
