Jannik Sinner fended off a battle from Paul at Arthur Ashe Stadium in New York to advance to the US Open quarterfinals on Monday. Sinner won 7-6 (7-3), 7-6 (7-5), 6-1 in straight sets in a thrilling battle at Arthur Ashe Stadium. That knocked Paul out of the US Open and ended his second straight run to the fourth round of the tournament.

This was Tommy Paul’s match — even with No. 1 Jannik Sinner standing on the other side of the net — at Arthur Ashe Stadium. All he had to do was manage to pull off the upset.
