Ana is through to the last eight of the JPMorgan Chase Open with a comprehensive 6-1, 6-4 victory over world No.16 Anna-Lena Groenefeld.

Ana made a bright start, serving an ace in the first game and breaking the German immediately to move ahead 2-0. She clinched another break and led 5-0 after just 14 minutes. A fourth ace helped seal an opening set that was as one-sided as the 6-1 scoreline suggests.

That Ana was able to break Groenefeld two times out of three in set one was especially impressive given that the sixth seed produced a first serve percentage of 70.

Groenefeld stopped the rot by holding to 15 in the first game of the second set, then held a break point for a 2-0 lead. Crucially, Ana saved it before levelling with an ace.

The 18-year-old scored the decisive break in the fifth game and comfortably held to 30 as she sealed an impressive win.

Ana served six aces and was not broken during the 68-minute match. She converted all three of her break point opportunities. "I have very high goals and I want to reach them," said Ana.

"It doesn't matter who I play, the most important is to play my game. It was a good match and my service was working really well. I am really pleased.

"Groenefeld is an aggressive player and I was trying to move her around. That was important. Even if I lost a few points, it was a good thing to do."

Ana will face her compatriot Jelena Jankovic in the quarter-finals on Friday. The 21-year-old, who is currently ranked No.28, beat Samantha Stosur 6-4, 6-1.
