The World No. 46 controlled their first meeting with aggressive baseline play and converted key opportunities against his fellow American.

Michelsen broke in the eighth game of the second set before serving it out at love. He maintained his pressure in the third set to complete victory without facing a major scare.
The result marks another impressive US Open run for Michelsen, who is now into the tournament’s third round.
