Riske was in good shape in her first match here two days ago but Mertens looked so tired at the moments and that allowed Riske to control the match. Flipkens is lower on the ranking but she can make an upset if she will have good day like against Tomljanovic in the first round.
Riske leads 1-0 but that match was played on hard. I hope Flipkens will win in three sets.
