A Court 1 match where the #2 seed could find herself in trouble.
While the Russian, Zvonareva is a decent player on grass, it's Riske's best surface. A strong start from the American, Riske could pose problems for an emotional Zvonareva.
The two have never played before, but I expect a close see-saw match with Riske pulling out the upset in the end.
Three close sets with Riske winning the third 7-5. The biggest upset of Day 1.
