How does a difference in scoring like this happen?
On the same bill, welterweight Timothy Bradley was held to a split draw by Diego Chaves, despite appearing to outwork the Argentine.
Bradley was returning after a rematch points defeat by Manny Pacquiao, but endured more frustration as one judge scored it 119-109 for him, with another carding a 114-114 tally, while a third gave it 116-112 to Chaves.
