It's pretty simple with Serena... You either have a serve or you're toast. That's why Hradecka managed more games than the top 2 players in the world.
Maria most definitely has one of the best serves on tour (see Stuttgart), but it completely vanishes in this match-up. Until she stops shaking in her skirts and stop serving trembling from fear, she won't ever beat her. Simple as that.
Can't wait to see Maria's sliding BH winners in Rome
