Well, he is No. 17 in the YEC race and only 200 points out of the No. 12 spot.
He is grouped in with Tsonga, Querrey, Busta, Raonic, and Nishikori.
Might be tough for him to finish at No. 15 this year, but it's probably just as tough for him to finish No. 12 or 11.
Then you have next season to pick up some points early, especially AO where he will have a great seed (lost in R64 this year).
So 10-15 is the safe bet I think, but hitting top 10 is certainly possible.
