Good stuff, though in truth I have difficulty getting enthused about Marcus beating a WR 469.
It makes you wonder what level Marcus could be at if he was playing tennis seriously? I see he is entered in all 3 futures events this month, so at least giving it a go for now. Looking at his results over the past year, there is everything from wins over top 200 players to losses to 700 or below; he is probably playing at a top 400 level but surely if he gave it a proper concerted effort he would really be playing Challenger tour events and hold a ranking in the top 200?
