i was playing at my club a couple of weeks and i was being an idiot trying to chase down every single ball. i went to lob this ball that was probably 15 feet behind the baseline, i got to it and made perfect contact, but unfortunately i also made perfect contact with the back fence at full speed. there was some wiring holding up the canvas and it had a nail like end which ended up cutting open the left hand side of my chest from front to back. i toughed it out and tried to keep playing but i had to stop once i realised the side of my shirt was drenched in blood. and people say tennis isn't a contact sport!
