Agreed, Lady TT. Alexandr Dolgopolov is a joy to watch when he is in full flow. He just flies around the court. Unfortunately it is taxing on him and his condition, Gilbert's Syndrome, which affects the liver, blood and often causes exhaustion. His condition worsens when he has to have extensive travel over long distances. If he were able to have more stamina, he could be very dangerous. He is almost forced to gamble a lot and risk, and therefore he usually has a lot of errors. When he can cut those down a bit, and his winner/ue ration improves we see he can win against top quality players.
Respectfully,
