McLaren mechanic keeps job after Button failure

The McLaren mechanic who cost Jenson Button his championship lead has kept his job but is "devastated", according to team boss Martin Whitmarsh.

On the Monaco grid, the mechanic forgot to remove a cooling bung from the sidepod of Briton Button's MP4-25 and the engine overheated.

"When you are trying to do your best and you make a mistake it is devastating," said Whitmarsh.

Button, 30, was initially angry but he later acknowledged that mistakes happen.
