Meusburger won the first nine games against Estrella Cabeza Candela and never looked back in her 60 62 victory. The Austrian converted on five of nine break point opportunities compared to zero of three for her opponent, and also won 10 of her 13 second serve points and 15 of 19 points on Cabeza Candela's second serve.
"I'm very happy that I won today because I had some serious problems with my neck last night," Meusburger said. "I'm just happy I could play, and I ended up playing solidly with few mistakes. I served pretty well too. It was just amazing."
Meusburger has lost just seven games through two matches and after having not reached a WTA quarterfinal all year before Katowice two weeks ago, has now made two straight.
"Clay is definitely my favorite surface," Meusburger said. "I have confidence in my game and I'm looking forward to the next round.
"I love Marrakech. It is beautiful. Yesterday we went to some nice places, like the Medina of Marrakech. I've never seen such places; it's amazing. The weather is really nice and the people are so kind and generous. I hope I can stay as long as possible and I'm definitely coming back next year."
In order to stick around longer, Meusburger will need to get through Romina Oprandi. Down 2-1 in the third set against Beatriz García Vidagany, the Swiss won five consecutive games for a 62 57 62 triumph, improving to 3-0 in their head-to-head.
Hercog is playing just her second tournament of the season after retiring with a right shoulder injury in the first round of the Australian Open. But after scoring a 61 64 win over Alison Van Uytvanck, the Slovenian finds herself back in the quarterfinals at the same event where she reached her first WTA quarterfinal in 2009. Torró-Flor never faced a break point in her 61 62 rout of Lara Arruabarrena and like Meusburger, has surrendered just seven games through two matches.
