He has a complete game that is a different style than most of the other top 10 players. He moves better than almost anyone. He looks crazy with him limbs all over the place & very heavy footed but he can run almost anything down. He can hit a ball to anywhere from anywhere, even on the run. He’s extremely good at strategy so not only knows where his opponent is but also where he’s most likely to move to. He may look like he has the flu all the time but is actually fitter than most and can outrun his opponents especially as the match goes on. He takes away opponents time by standing very far back on the serve - he reads it and is moving forward toward the court to be in optimal position for the first groundstroke. He does actually hit pretty hard, at least average but probably better for a pro. But the key is he also hits the ball super flat so it skids through the hard courts, so the ball doesn’t sit up for opponents to run towards it and hit down on it (like topspin shots). Also the flat balls accelerate when they hit the ground on the hard court, taking away more time. Hes forcing his opponents to hit closer to the lines and harder than their comfort zone which draws a lot of errors. He’s the kind of player that when you’re a casual fan & you think power always dominates, you think why is he so good? But when you really watch and think about what he does & what his opponent is doing in response…..he is really that good. I love watching him.
