Not Top 100 at the moment, but still I was hugely surprised not to see a thread about him in here.
He played an outstanding tournament in early January in Doha, winning 6 matches in a row from qualies onto the semifinal where he lost against Rafael Nadal in 3 sets.
He has wins over Thiem and Kohlschreiber (in Doha) and he qualified for Australian Open 2014.
The last weeks were bad and he had some injuries.
This week he'll play Munchen.
What can we expect?
Is he healthy again?
