I think it's Quevedo, both Spanish girls got wildcards into qualies.
Carolina Quevedo being Kaitlin's sister?
Or is that Sofia?
No idea - hadn't heard of any Quevedo's before this week. Carolina is 25 - there is a Kaitlin who is just 17 and a top junior (who I assume you mean). It seems to be a common surname in Spanish speaking countries.
