When was the last time Andy went out in a Slam as early as this? Why is it that he's far more consistent in Slams? If you can get that through your brain, really.
Andy's played this poorly in Slams before. It's just that in Slams it's best of five and psychologically that weights on both players minds. Keeping it up over 2 sets is one thing, but over three sets nigh on impossible and Andy will eventually play himself into it.
