Serbian coach lost this game, awful decision to let Micic finish the game while letting Avramovic on the bench that was on fire and is a better defender
It's not the only country that had been caught doped, athletes from many countries have cases in differents sports, even the US. Just because a chinese swimmer won comfortably doesnt mean he's doping
Of course the usa is always the good people that follow rules and China the bad that cheats on everything, it's not your fault that you believe that tho, it's what they teach you there
It wasn't a draw thing, and i would say his draw wasn't bad at all. He never reached his potential because of his backhand and his limited mental strenght, if you look at his better results, most were against players of his level.
He had an injury recently and wasn't at 100% and singles is way more demanding physically than doubles. Plus clay is his worst surface and a 1R draw vs Struff wasn't the best, I think he made the right choice (Nadal should have done the same)
