Ana was unable to reproduce her recent form and was toppled in three sets by defending champion Timea Babos in the second round of the Monterrey Open.
Babos defied her ranking of 123 with some heavy serves that immediately put Ana on the back foot. It was clear very early on that Ana was going to have her work cut out, in contrast to just 24 hours previously when she triumphed 6-0, 6-0.
For only the third time in her professional career Ana recorded a perfect 6-0, 6-0 result: she beat world No.116 Marta Sirotkina in the first round of the Monterrey Open without dropping a game.
Sirotkina was playing in only her second WTA main draw match, but one would not have known it from the assured start she made in the opening game: she was solid from the ground and earned a break point.
Ana will take on world No.121 Marta Sirotkina of Russia in the first round of the Monterrey Open, which begins in Monday. Ana's match is expected to take place on Tuesday.
Should she overcome the 22-year-old, who will be appearing in only her second WTA main draw, Ana will take on either defending champion Timea Babos or Mexican wild card Ana Sofia Sanchez.
Sixth seed Yanina Wickmayer of Belgium could await in the quarter-finals, while second seed Marion Bartoli is a potential semi-final opponent.
Ana has entered the Porsche Tennis Grand Prix, which takes place in Stuttgart during April 22-28. It will be her third appearance in the event since it switched to indoor clay in 2009.
As of today, Ana is the 10th highest ranked player in the field. The leading contenders for the title include world No.2 Maria Sharapova, No.5 Na Li, No.6 Angelique Kerber and No.7 Sara Errani.
Ana has accepted a wild card into next week's Monterrey Open, a $235,000 hard court event.
“I am so excited about playing the Monterrey Open, presented by Heineken," said Ana. "I love visiting Mexico and this will be my first time playing there as a professional.
“I played some junior tournaments in Merida and Mexico City and had a great time. The best holiday of my life was to Cabos about five years ago, so I have nothing but positive memories of Mexico.

In spite of a marvelous opening set and a striking comeback in set two, Ana fell 1-6, 6-4, 6-2 to world No.8 Sara Errani in the fourth round of the Sony Open Tennis in Miami. Both players won exactly 79 points during the 103 minute encounter, but the Italian proved the more consistent player in sets two and three.
