Thiem has a fantastic all-round game. Wicked groundstrokes, powerful serve, great retrieving, decent return. The thing that separates from other players his age and ranking is his consistency with them though - most other players have the weapons but will often error every 5th or 6th shot. Mental strength is the big unknown though, and it is that that separates the very best from the rest. He's clearly a very confident player, but he's also got the advantage of being quite unknown to most players on tour. Once they start working him out it will be interesting to see how he fares. Harrison for instance has gone completely backwards since breaking through, likewise Tomic and Young.
That's a good point.
It's interesting, it does often work out that newcomers to the tour seem to get a free 12 months or so, because their games are an unknown quantity. It fascinates me to see players working the youngsters out.
Thiem can obviously play, but staying with someone like Andy in a best of three is a different kettle of fish to doing it in a slam, as is doing it not just once, but week in week out.
It will be interesting to see how Thiem goes on. I hope for his sake he isn't hyped too early. I hope he's given time to find his feet first.
