There have been a lot of great action shots this week - snapshots of some, well, great shots.
Ana Ivanovic and Garbiñe Muguruza put forth some strong serving displays in the Spanish capital...
But Serena Williams, the world's best server, served up 11 aces in two of her first three matches.
There have been some massive forehands on display too, not many much bigger than Li Na's.
Sloane Stephens is a natural on clay, her retrieving skills - like on the forehand - second to none.
One of the fastest players of all time had some rock solid defense too, even on the practice court.
And then the other wing - Belinda Bencic and her big backhand played Williams in the first round.
Sam Stosur is also a clay court natural, reaching the third round before falling to Maria Sharapova.
Caroline Garcia was the breakthrough star of the tournament, making it all the way to the quarters.
Carla Suárez Navarro has one of the most beautiful one-handed backhands in the women's game.
But she's also a relentless retriever...
Trying anything just to put one more back in play.
Svetlana Kuznetsova nearly slid by Agnieszka Radwanska in the second round, holding three match points.
Simona Halep's favorite surface is clay, though she openly admits she's playing even better on hard.
And finally, the clay kicked off the shoes of Sharapova - cleary a French Open favorite at the moment.
