Considering his lack of running due to P1/P2 problems for Alonso he did very well to get the car up and as fast as he was, and judging by the Q2 times most of the top guys gained a few tenths partially track getting more grippy, partially the top guys holding something back for Q3. Shame for him but, had he not pee'd around early in the session I think he could have put in a much better lap.
Something may have broken at the end or the mistake may have fluffed that last lap completely. Funnier still was Massa did a significantly faster lap without the tow at the end, complete waste by Ferrari. Did he have a real problem or did they see an excuse to swap out for a new gear box/other parts anyway, its not like the car won't find it . The final sector doesn't mean anything, one big mistake and they knew he was done and would struggle to get above 10th anyway so there wasn't any point pushing.
Take a hit now, have as fresh and fixed a car as possible for this and the next race. Maybe, who knows. However they sent him out for another run after the first one, it clearly wasn't working that badly. Not doing a banker lap and then IF Massa was struggling maybe try and help him at the end was mental, that was a Mclaren style tactical smeg up.
