It was raining, cobbles are treacherous in the rain, so the officials nullified the intermediate sprint bonuses. They were unclear about whether they just meant the intermediate bonuses or all sprint bonuses. Vino's team understood that only the intermediate bonuses were gone so he attacked and won and leapfrogged over Leipheimer in the GC. Everyone was a little pissed and confused. He used better tactical knowledge to do it but he put a lot of tired riders at risk of DNF. I'm surprised he didn't end up in a ditch in the next race.
