I've been following his progress since 2008, when I noticed him consistently getting to 3R and 4R of the majors. Watching him step up in his first three tournaments of the year was quite impressive. Most impressive has been his maturity at his age and his ability to put mistakes behind him and focus on the current point. He has an excellent first serve and a very effective high kicker for a second. His forehand, while tentative, is very versatile as he can flatten it down the middle or spin it away to create an angle. Same with his backhand. His return of serve is very effective, especially with his long reach, and his movement is fluid, which could mean that his career will not be riddled with injuries. He has the potential to be a complete player if he can stay on course to develop his game. And given his mentality, I believe he can. Barring injuries, I believe he will be a multiple major champion in the future. As I said, very high hopes.
