I woke up an hour ago and saw the result, and went back asleep thinking about other things. I wasn't disappointed, or shocked, because this isn't a surprise. I didn't feel the usual. It could have happened in the first round, to be honest, if Coric had been able to force a fifth. That kid looks like an exceptional talent. But Rafa also struggled against Peter Dinklage in round two, so losing to Fog in a rollercoaster match of mishaps and dropped serves isn't a huge shock.
It is disappointing, because it's Rafa, but I didn't feel anything remotely like sadness or disappointment. We've all seen him this year, and to be honest, he hasn't been himself since the Oz final in 2014. In fact, go back further and after he won the US Open in 2013, his intensity levels dropped and he coasted for a while. The great furnace that raged on the summer hards that year has been seen rarely since, maybe only a couple of times on clay last summer.
He's showing natural signs of physical wear and tear, it happens to players of a certain vintage, especially when they have so many titles in the bag, and so many miles on the clock. It happened to the great Pete Sampras, too. His mental toughness has been replaced by panic and doubt. He's timid in the clutch and his shots don't carry the physical force or threat they had in the past. Since he came back this year, he's worked hard but he's not the same. Everything takes its toll eventually, and though there's no cure for ageing, I suspect he'll play a lot better before his career is done.
Fair play to Fog, it seems like it was a terrible and great match, lots of spills and mishaps, and he did a remarkable thing to turn it around in his favour...
