The turning point seemed to be during his semi final at Hamburg where he had Nadal on the ropes. Hewitt seems to have regained the intensity.
Lol why is it called the lawn mower??.
I have noticed a big difference in his body language. The "come'ons" are back and he also seems alot sharper around the court. Hewitt's serve and return during the championships could be the key formuale to his rise back to the top.
