Venus or Serena Williams for US Open title?

Will Venus Williams' surprisingly poor post-Wimbledon performances damage her prospects at the U.S., which begins Aug. 31? Probably a lot more so than for her sister, Serena, who seems be able to turn the victory spigot on and off at her pleasure.

Venus last won the U.S. Open in 2001, a year in which she played 11 matches leading up the final Slam in New York, winning 10 and gaining titles at San Diego and New Haven. She had heavy momentum going into the that Open, where she took down her sister in the final. A year later she was undefeated in 13 post-Wimbledon matches and reached the final at the Open, where she lost to Serena. Again, a lot of play, a lot of match toughness and a strong Open.
