Mine went to Alonso for his overall weekend performance - up there with the RBRs in all three practise sessions, as close as he could get in Quali when the RBRs always perform (in Q3) to their full potential and, in the race, he managed to hang on to a leader who was clearly having an easier afternoon.
The first part of P3 on the primes was so telling of that - Alonso was driving the Ferrari to it's limit, and a couple of times almost over it, to set decent times - then Vettel came out and threw in a first timed lap 0.8sec faster and then rubbed it in with 2 or 3 more that were almost as fast ..... when they went onto primes it was similar, with the difference a bit less.
(BTW, I'm quoting from memory so don't shoot me down if I'm out by a tenth here or there
)
I can see why other votes have gone with Alguersuari (good race result from a lowly grid place) but he was beaten by team-mate Buemi in P2, P3 and Quali despite Buemi having to sit out P1 being replaced by Ricciardo - DotW not Dot-Race!
Vettel had a very good weekend overall (pole, win, fastest lap) and if he'd pushed the RBR in the race, won by 45 seconds and lapped everybody up to 4th/5th he might have edged it - DotW not Result-otW!
