Ana emerged with a lot of credit from a highly-entertaining clash with world No.2 Maria Sharapova, she but was unable to reach her first semi-final of the year as she fell 7-5, 4-6, 6-4 at the Porsche Tennis Grand Prix in Stuttgart.
The 25-year-old was close to scoring an upset over the defending champion and top seed but, crucially, she could hold serve only once in the deciding set as she tasted defeat after two hours and 16 minutes.
Ana reached the last eight of the Porsche Tennis Grand Prix in Stuttgart with a 6-4, 6-3 victory over world No.11 Nadia Petrova. With today’s win in 80 minutes, she extends her winning streak on clay to four matches as she continued her fine form on German soil.
Despite the comfortable straight sets win, it took the 25-year-old some time to produce her best tennis. She was broken in the third game, fell behind 4-2, and twice faced another break point for a double-break deficit as Petrova began as the more aggressive player.

The world No.17 maintained her fine form in the second set and it was the home player who showed greater nerves, as Ana broke to clinch an impressive victory.
