With a single match lasting 2-3 hours and having to play like every other day. For example, Baghdadis will have played on August 1,2,3. Don't they get sore and tired as hell? I have never played tennis in my life but i would imagine it being very energy consuming sport with all the changing of directions, serving, running back and forth, using the whole body etc. Isn't that like playing soccer 90 mins for 3 days straight?
