I think he can break into the top 100 for sure, he's been playing extremely well the past few weeks, just won his first futures title defeating the top seed in the final, and he is improving his game with every match. In two of his matches this week he's lost the first set and been down a break but come back to win and that's important for confidence, so I think for sure he can build on this and get his game to a higher level and eventually break into the top ten
He is currently ranked 445 and I think he will move into the top 400 after the Sao Paulo challenger. Amazing considering this time last year, he was practically unranked. He is only 19 so there is going to be lots of chances for him in the future. For sure he will probably get wild cards to play Costa do Sauipe next year (his mother is Brazilian and he spends a lot of time there) and to Bastad and Stockholm next year to get more tour experience and ranking points. He got a WC to Bastad this year and took Nieminen to three sets.
