Jankovic scored a 6-4, 7-6(8) after nearly two hours to snap a four match losing streak.
“I found it pretty tough moving from clay to indoor hard, where the ball goes very low and fast, so I found the adjustment quite difficult,” Jankovic commented. “Laura played really well, but I knew I had to hang in there. I was a little nervous as it was my first match here, but I’m glad I managed to come through with the win.”
In second round action, Kaia Kanepi beat Hungarian teenager Timea Babos 7-5, 4-6 7-6(2), ending the match with her 12th ace.
“It was a difficult and really long match,” Kanepi commented. “Timea played really well and pushed me all the way. Thankfully I played a really solid tie-break, cut down the errors and came through. Spending two and half hours on court is tiring, but I’ll be ready for my next match.”
Also through to the quarter finals are Mona Barthel, Petra Martic and Alizé Cornet.
