Machado started to play 2 months ago. He is much better than Dutra Silva, even with his absence from the tour, he should start to win matches like this, or he will never climb up to where he belongs. I still expect him to win this match as he should. He has to be back where he belongs, as soon as possible.
Lol, started to play 2 months ago in Future where he almost couldn't play one week at his phisically top. This is his 2nd Challenger tournament, is completely different. Now he isn't better than Dutra da Silva, Rogerinho is on fire and Machado is far away from his best.
Why are you so nervous? "He should start win matches like this". Mate, this is his 2nd Challenger tournament, you wanna miracles? How many time Del Potro needed to come to top? Devvarman came from a long injury and he stills without reach his old level. Calm down.
