Why are the Serra-Zanetti sisters going downhill?
Outside the Williams and Clijsters sisters, the only other real intriguing sister story, (for the moment anyway since the Uberois are slowly making a splash) have been Italy's Adriana and Antonella Serra Zanetti.
Niether player seems to be Italy's best bet for success, but I was intrigued when they where doing somewhat well and both had been in the top 100.
When I saw the ranking today I was shocked at how much they have sank in the rankings. First Adriana seemed to move down after her Australian Open result a few years ago, and now Antonella seems to have done the thing, and is now ranked lower than older sis is.
Anybody know what has happened to these two and do you think they can get it together and at least be back in the top 100?
