Re: Serena and Maria are in the best shape ever
Maria is definitely at her physical peak, she's never been better at recovering from matches or had such high endurance levels and her movement is always improving. Hopefully the days of Maria moving slower than Robson are gone for good.
Serena is in great shape too although I'm not sure whether she's physically just as good as she was in 2002-2003 but the current level is still damn impressive.
I don't think Serena will ever be as fast as she was pre-2003, but she seems to be better in all other aspects.
