It is almost like Roger Federer needs to think more and Marin Cilic needs to think less. You would say to Cilic, 'no more thinking, just bombs away'.

I would say it's neck and neck right now in terms of who is playing best. Querrey has pegged Raonic back a little bit. It was always going to be difficult for Raonic to continue playing as he did in sets one and two.
*Querrey 4-6 5-7 7-5 3-4 Raonic
These two have the crowd ooohing and ahhing all over the place.
The Court One pair are locked in a brilliant rally and Raonic tracks back to the baseline to chase a Sam Querrey shot as he tries to send backhand down the line with his back to the net.
It doesn't quite make it - it lands just wide of the whitewash - but everyone appreciated the effort.
Raonic holds and we still go with serve.
