Hopefully, he will soon switch his focus from Asia-Oceanian challengers to ATP main tour. There is absolutely nothing left for him to do in the field where he's currently playing. It was probably a wise decision not to throw him into the big boys in ATP too soon, but he needs to experience the tough world of the main tour as soon as possible. He got some small taste of it in Miami, and looked very promising. His defense and ability to switch directions were impeccable.
