Murray loses another match against a decent a opponent. It's becoming a pattern. He's only managed to beat Simon and Lopez this year, and he always beats them. He's even lost to Cilic, whom he owns, Federer, whom he should not be losing to anymore, and Dimitrov, whom he had never lost to prior.
I'm really worried, not just by the losses, but how he lost them. He seems to be lacking both the stamina and the belief in crucial moments. I'm starting to think he'll never get back to where he was.
