Robbie is not under any threat of losing his jersey today. Boonen is 29 points back, Freire is 30 points back, and Bennati is 46 points back.
With only 4 riders in the break Robbie still has a chance to take points from the bunch sprint at the finish, even if they are only 5th place points.
VElonews is saying that if Friere wins the stage and McEwen gets no points he takes the green. I was going by that.
