Both Toni and Nadal knew fully well what the slams comprised of when he took up tennis as a profession. Ralph knew there were 2 HC slams and 1 grass slam,that's 3 out of 4 slams for basically shotmakers but instead he chose to be a grinder.
So,choosing to be a dirtballer is Ralph's fault,not the ATP's. If anything he should thank his stars they slowed down everything,even USO to suit his style of play. And yet his uncle has the audacity to complain. How selfish are the duo?
