Aussie coach Darren Cahill nods support for his player from a Halep player box with plenty of Romanian red, yellow and blue.
He has been through some times with Halep, good, bad and quite ugly. The WTA Tour allows on-court coaching, and Cahill can often be seen in the role of counsellor as much as coach in some of Halep's darker moments.
He's not quite Ivan Lendl, but has understandably chosen a low-key player-box attitude, such are the wild momentum swings he often has to endure. Cahill has certainly reinforced his reputation as one of the best coaches out there, however, helping Halep to the top of the rankings. It's just that Grand Slam title they need...

The German press man who was inconsolable after the first set is rocking backwards and forwards and laughing uncontrollably - which is pretty much the reaction from everyone after that break point. Incredible stuff, and long enough to go through about three gusts of winds, just to make it even trickier.
