She is becoming so much of a complete player.

Right then, what has Sloane Stephens got in response to that opening Johanna Konta blitz?
The American edges to 30-15, putting some good depth on her baseline strokes, but then flings a backhand long after Konta's return jumped up off the net - Stephens twiddles her strings looking for an answer - 30-30.

Daniela Hantuchova
Former world number five at Roland GarrosSloane Stephens was shaking her head at the end of the set, having to accept that Johanna is playing this well.
She will be trying to work out how to change things but the way Konta is playing I don't think there is much she can do.

Wawrinka 5-4 *Federer
Image source, GettyThis is a real tight-rope walk of an opening set. Stan Wawrinka's serve has come under more pressure, but he has found the big shots to keep Federer at arm's length.
Can he tweak up the pressure on his compatriot in this service game? One slip at this stage of the set and Federer is fondue.

BBC tennis correspondent at Roland GarrosBefore the match I thought Stephens might have a little bit too much for Konta but at the moment there's only one player in it.
Stephens will have to press the reset button to try to find an answer to the way Konta is playing.
