Both events were previously firmly opposed to any sort of coaching but now they are joining the Australian Open and the US Open in allowing that to happen. It's been something that has been talked about for a long time and slowly but surely coaching is starting to appear in tennis which makes some players happy while others continue to oppose it.
Tennis first allow coaching from the stands last year with events slowly starting to adopt it. Australian Open allowed it this year with Roland Garros following suit. Wimbledon was initially opposed to it but now they will follow suit.
