maybe he is just getting matches under his belt so he will be ready for the Australian open.
who knows what the hell he is thinking but all this tennis activity is way too risky at this point. this is how he has always gotten injured. he overdoes it.
I would rest at this point and train a little bit on clay to keep the ground game sharp. clay is also easier on the joints for him.
But possibly playing Beijing/Shanghai/Basel/Paris/WTF is way, waaaaay too much! I don't know what Rafa's thinking but he better take some rest before WTF.
