He faces the worlds number 25
Isle of Man professional tennis player Billy Harris will be making his debut at the US Open later today (26 August).
The former Albany and Castletown competitor is due to face world number 25, Canadian Felix Auger-Aliassime at the Billie Jean King National Tennis Center in New York.
The game is due to take place on court 17, at 6:50pm UK time.
It'll mark the first meeting between the two players on the ATP tour.
It is the first time Harris has qualified for the main draw of the event, despite losing his third and final qualifying game to Hong Kong's Coleman Wong.
He was awarded 'lucky loser entry' after players had to withdraw from the competition.
In the first qualifying round he beat James Trotter from Japan, and followed that up with a win over Mikhail Kukushkin from Kazakhstan.
