Race leader Lewis Hamilton had a handy 25s lead by Lap 64, when the Safety Car was deployed, and Mercedes called him in for a precautionary pitstop for new tyres. Hamilton complied thinking that Nico Rosberg and Sebastien Vettel would do the same. They didn't!
Rosberg took his third Monaco victory in a row, and Vettel finished second for a great win for Ferrari. Hamilton came 3rd, no doubt grinding his teeth!
