He did 2 laps in Q1 and 2 laps in Q2 so I don't think he had 2 new hards. He looked really competitive until few laps before his second pitstop and then his pace dropped like a rock and never really recovered.
I haven't seen the data yet or heard reports, but it looked like the classic balance change problem, Jensons car worked better in the second half of the race and Segio's on the first (due to fuel amount difference). During Q1 it was obvious that Jenson was very good on low fuel+Hard tyres.
Sergio was doing very well the first half and unfortunately he left an open door for Rosberg which he duly went for and Sergio defended it "robustly". A touch more "spatial awareness" and he would have been ok.
Good first stint by Sergio. Impressive Last stint by Jenson, overtaking both FI and Massa. Job done.
Edit: ok.. so front wing set false.
