Once again Sara shows her big heart by beating Suarez Navarro 7-5 4-6 7-5 in a tough 3 hours match.
Sara had a tricky history with the Spaniard that has just upset her in the Australian Open first round, so it was time for the Italian to take revenge.
Errani is the only seeded player to reach the semifinals as Bartoli, Kvitova and Safarova crashed out in the quarters.
The Italian will play lucky loser Kiki Bartens (61 7-5 on Safarova). Head to head is 1-0 for the seed no 1.
In the other semifinal erratic Mona Barthel (7-6 (7) 6-4 on Bartoli) will play surprising French Kristina Mladenovic (6-3 6-4 on Kvitova). Wildcarded and ranked wolrd no. 87, the French teenager is having an incredible tournament to defeat Goerges, Wickmayer and now Petra Kvitova.
