Sixth seed Li Na of China, the Australian Open finalist, moved into the last eight thanks to a 2-6, 6-2, 6-1 win over Italian Roberta Vinci, who won in Barcelona last week.
“The first set was good for her, then I started thinking about hitting it more to her slice backhand,” Li said. “After Melbourne, I wasn’t winning any matches, so it’s exciting I’ve now won three matches on clay. Things are going fantastic. Since my new coach joined my team, I’m happier. I have more good energy now.”
