Yes, I have noticed this too. She struggles against Dementieva, and Venus Williams whose 2nd serve is appalling too, and now Kapros. Something Carlos should be looking at I think. I suppose she has been concentrating on how the majority of players play their 2nd serve which is quite right. She just needs to expand her repertoire further. It just goes to show that her game is nowhere near complete and yet she plays so well. She didn't serve or play well herself today though.
