Naomi's team decided she needed some experience on Clay, her least favourite surface. So far it is paying off very well. Her next opponent knocked out Lertcheewakarn, and will be playing on her favourite surface. So it may be harder than it looks on paper.
Sounds like a wise move by Naomi that will hopefully help her a lot in the long run. Good luck to her in the next match and for the rest of her Croatian trip.
