Thanks DF, I knew she was on first but assumed it would have been 7pm, but just saw the US changed their clocks last night, so 6pm (or just after) it is. I would have preferred it to have been 7pm personally, but this is good news overall that some of the later matches will be starting an hour earlier from now on.
Hmm I can't see Emma's match listed on Amazon Prime for this evening- surely they will be showing it?
Strange, bit no, it isn't listed on the website, although over 30 other matches are, including doubles. uist be an oversight, and I expect it to appear closer to the time.
