Quarterfinal Previews for July 22, 2011

It's quarterfinals days at the two ATP World Tour events and the lone WTA Tour event this week. Unlike last week's Stuttgart event that featured no seeds in the quarterfinals, Hamburg seeds are in each quarterfinal spot this week. In Atlanta, at the first US Open Series event, the top three seeds survived the opening rounds. On the women's side, the Baku, Azerbaijan event's big story has been the service motion change of 2nd-seed Anastasia Pavlyuchenkova. In multiple matches she's thrown up over 20 doubles faults.
