Hamilton balks at Jekyll and Hyde car again: 'Don't expect much from it'

So many times this season the Mercedes has proved to be something of a Jekyll and Hyde, and on the opening day for the Grand Prix in Miami it was no different. Ahead of the sprint race, Lewis Hamilton is already tempering expectations after his car let him down in the Sprint Shootout.
