New boots on, Lewis Hamilton leaps to the top of the timesheet with 1:45.765.
All is well in the world of Mercedes? Not quite because Daniil Kvyat knocks Hamilton down a peg, going more than four tenths of a second faster. You don't often see the Mercedes making the switch to the softer compound so soon too.
