18:15 CET - The latest update from Miami is that there will be no play until 18:30 CET and that is expected to be pushed back further. The rain may have let up for the moment but more rain is forecasted and play may not get underway until the evening in Miami which would be overnight in Europe.
15:20 CET - As expected, we are going to have a delay to the start of play in Miami with the organisation announcing there will be no play before 12:00 local time (17:00 CET). We will bring you updates once we have them if there are any changes.
15:00 CET - Hello and welcome to our Tennis Tracker for what promises to be a fascinating day in Miami!
Unfortunately, after a day of bad weather that curtailed play on Friday, it is back again with a delay to the start of play seemingly inevitable. Lightning strikes have been reported in the area and the gates remain closed to the public. They were meant to open right about now with play to get going at 16:00 CET, but that feels an unlikely proposition. As soon as that changes, we will bring you the news.
