baseball / softball aka shitball! bag o bollocks.
like beach volleyball, what the fek is it doing in the olympics in the first place?
baseball, a national sport in cuba, america and japan (and a tiny bit in canaduh. hardly good for international interest.
now cricket.... (the one day, finite number of overs variety; not the never ending test match, egg sandwiches and cuppa tea type nonsense) would be a good addition; you have teams from europe, asia and the antipodeans... plus even a growing following in the US (to a tiny extent).... that would fit the venue at least.
meanwhile, BMX rahhhhhh! tip top choice!
incidentally, did phelps really win his 100m butterfly gold?
