I can see him in F of slam in next 2-3 years it can be on every slam outside of RG. If he will be in F here at USO than it will be one of best runs ever- Verdasco, Fish, Federer, Djokovic .... so if he is going to make it to F here than impressive if those guys will advance too. But i don´t think he will make F now, but how i said in next 2-3 seasons AO, WIM, USO most likely has chance
Tsonga is Clownga. He can beat anyone if he's playing high level intensity tennis, but due to his clown-ness nature, he can never play two successive high intensity tennis, so no, he will never win a slam, but he might occasionally get to final if he gets easy QF draw.
