Unfortunately, Yates is the only one I can see blowing from the top four. Pozzovivo is well motivated. He made being captain for the Giro part of his contract deal, so he's going to go for it as is Froome. Dumoulin is strong but I think he'll lose time on the next two days.Dumoulin's options are limited today but I think the real danger comes from Pozzovivo. He looked very strong yesterday. If Sky stress the peloton and Pozzovivo climbs aboard, I can see Yates blowing.
It's going to be exciting, I'm off to the shops now before it all kicks off.
