Not that I'm qualified to set levels much above 5.0, but he's clearly got a nice looking game. I'd say 5.5 - 6.0 based on what I've seen of local players.
His footwork is exceptional...really impressive movement. His stoke mechanics are solid, but the backhand looks like it might breakdown if playing against hard flat balls...quick take back but there is a little hitch just before he strikes the ball (I realize I'm nitpicking here). Volley technique is solid...depth seemed a little short to start but improved as the video progressed. Serve/overheads seemed solid...very quick attack on service motion. Serve return also looked great. Unclear on how much variety in game this guy has. Need to see a game or two to judge that.
Who is it?
