Yeah, he is pretty young, and this has been his best season so far. But he's actually been around for a while already. He won the tour down under last year with Mapei. In that race he flatted and a spectator by the side of the road just happened to have a C-40 that was about the right size, and he lent it to Rogers, who regoined the peloton and kept control of the lead to win the TDU.
I've known he was a gread TT'er for a while, but I was a bit surprised he did so well on the summit finish in the Tour of Germany to keep himself within striking distance of the GC.
