After the 1-5 lead for Seppi , Kiefer surely looks emotionally pumped up and started off a fight here. Now he claws back to 3-5!
Yes, he is trying to fight , but I think it was too little and too late , for 1.set anyway. I think he is more trying to prepare himself for 2.set, to be in better emotional condition. It is very hard, he played 3 matches like energizer bunny, but human batteries dont last that long
