Petra Marcinko and Simona Waltert meet in the first round at Cincinnati on Thursday. Petra Marcinko comes in at 6 wins from the last ten. Simona Waltert is searching for form, having lost 3 in a row (5 of the last 10).

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. A tiebreak or two would surprise nobody, with Marcinko fractionally more likely to land the big points.
