Frances Tiafoe vs Alex Michelsen Prediction

Michelsen has been in fine form all tournament, but Tiafoe just came off a spectacular win over Daniil Medvedev. This matchup should also favor Tiafoe more than the rankings would suggest. Michelsen will look to control the match with the first two shots. His heavy first serve and powerful forehand, but Tiafoe’s return position and athleticism mean that Michelsen might have to tweak something or potentially engage in transition shots. Tiafoe will certainly rush him and bring him to the net if he needs to, with his variety. I’ll give he edge to Tiafoe.
