I'm not quite sure what you mean Bevc.
His losing % is clearly the worst in that rather insightful table youve provided against Rafa.
But then Rafa matured as a player a lot earlier than Andy and has played many more matches.
Hopefully he will start to turn the H2H a la djokovic in the coming years.
As they have all (the other 3) played each other much more than Andy has.
I'd wondered which player Andy had played the most times (you were talking about a lopsided H2H), and this was the best table I could find, and it would appear that Andy has played Rafa the most times (but I could be wrong) but yes, he has a poor stat against him, but lets hope that tide is turning.
