Serena sweating on Wimbledon fitness

PARIS - Serena Williams admits her dream of an eighth Wimbledon title could either be saved or shattered in a Paris doctor's office this week.

The 36-year-old American stunned the French Open on Monday by withdrawing from her eagerly anticipated last-16 grudge match against bitter rival Maria Sharapova just minutes before the two icons were due to clash on Court Philippe Chatrier.

A pectoral muscle injury had slammed the brakes on Williams' serving arm so she decided not to take up the opportunity to extend her 14-year, 18-match win streak over the Russian.
