No. 15-seed American Madison Keys takes on 58th-ranked Kiki Bertens for a spot in the quarterfinals at Roland Garros. Both are power players who try to impose their will on the opponent and both have the size and strength to do so. 

The stats below show how similar their performances at Roland Garros through three rounds have been:

  Madison Keys Kiki Bertens
Aces 15 12
Forehand winners 34 34
Backhand winners 20 19
1st serve points won 72% 70%

Here are the big differences so far:

Where Keys seems to have the edge is consistency and on second serves—both on her own and when her opponent has to hit a 2nd serve.  If those factors hold, they could be the keys for a Keys victory.
