Starting earlier than that would not make much sense really. Temperatures at noon in Acapulco will easily surpass 30 degrees Celsius and humidity over 60%. No need to do that when you can start later when conditions are better.With Sakkari, Bencic and Watson involved here plus potentially Lisicki as well, there'll be plenty of interest from me.
The only thing is, despite Acapulco being just 6 hours behind the UK, our coverage starts at 10pm over here, so that's 4pm over there - these North Americans and their 'late night tennis', eh. I was expecting it to be on around 11am over there which meant I could watch most of it when back from work around 5pm.
