Zvonareva 2.24, Pera 1.66
This will be their first meeting.
Zvonareva got her place in the tournament when Parmentier pulled out. She played well in the last round and lost just 3 games against Victoria Duval. She retired from her quarter final in an ITF tournament in the first week of the season and I suspect has not been 100% fit since. She certainly looked fine in the last match.
Pera came through in straight sets over Fett. Her serve looked a little vulnerable. She did well at the Australian open In January and reached the third round as a qualifier.
I see some value on Zvonareva. I think she can take a set.
Lay Pera below 1.45 and remove liability at 1.90. Decent chance of 3 sets.
