I agree that folks (like me), can make up excuses if it helps us, but I genuinely think he was not 100% in that Warwrinka match. The manner of his loss just wasn't like him. Today he went out there with the intention of wining of he could. I think he believed he would come off the court the victor, where he didn't seem to believe it in Monte Carlo. I can accept a bad day at office. If he had lost the match today on the tie breaks, it would have been because Mayer played so well. Murray didn't give anything away and fought for every point.
As you say, none of us know. Probably I am just soft.
Don't get me wrong, i am one of those that also think there was something up, for such a massive shift in form from his first match, i think his mind was elsewhere.
