The semi-final match on September 7 between Del Potro & Nadal ended up with Nadal retiring due to injury. DEl Potro was leading 2-0 in sets. So, I thought I had won as I had a tenner on Del Potro to beat Nadal. I was a little miffed when told that the match was deemed void by a bigname bookie; all I got was my stake back. Good news is that punters who had money on Nadal to win will also get their stake money back but unfortunately [like me] may have thought that Nadal got beat fair 'n' square.
