Britwatch

Brtish number one Johanna Konta has a tough assignment to begin with against unpredictable Russian Daria Kasatkina and Harriet Dart, a first-time qualifier, faces Romania’s Ana Bogdan. On the men’s side Dan Evans and Cameron Norrie have winnable ties.

Match of the day

Undoubtedly the grudge match between Serena Williams, the six-time champion, and 2006 winner Maria Sharapova. It might not be a classic of the past but the combustible American versus the ice-cold Russian will be box office on opening night.
