It's been a lot of bad luck. Go back to 2002. Kim was injured for most of the first 1/2 of the the year with her shoulder, Davenport was recovering until July, Martina Hingis had to end her career this year due to her foot. In 2003 Venus injured her stomach muscle badly, Amelie with her ribs right before Wimbledon, Lindsay injured her toe badly, Serena had to have surgery on her knee, Chanda couldn't defend her Los Angeles title due to injury, Monica was never healthy except for her 1st round match at the Oz, Jennifer hurt her back terribly at the end of the year. Now this year with Amelie and her back, Serena and her re-aggrevated knee, Venus will her ankle, Justine with glandular fever, Kim with the rist, and Jennifer with her back again. All of the elite players have had injuries this year. I never would've guessed that 2001 was the last really good year on tour!!
