Del Potro has won Estoril Open.
Andy certainly needs to avoid Del Potro, Berdych, Raonic , to name a few, if he is to keep his run of Semi appearances in Slams going.
Im just watching a rerun of Andy versus Berdych in Dubai this year. Andy is 3-0 up and won the first 7 points. Its amazing how easy it is for Andy versus Berdych on a fast hard court as against a slow clay court. Its a completely different match.
I think when it comes to slams, Andy will put his game face on and won't have the same lapses as MC and Barcelona. There's no guarantees Raonic, Berdy and Delpo would get that far to face Andy.
Perhaps it's just precaution to pull out but then again, a lot of people don't seem to like the blue clay saying it's got a bad bounce and is quite slippery so injuries to Monaco and Bennetau is bound to play on the minds of players still.
No one wants to risk serious injury before RG.
