The slimmest of margins decided the second set as Jannik Sinner captured the tiebreak 7-6 (5) against Tommy Paul.

Neither Paul nor Sinner were broken in that set.

Paul was up 5-4 in the tiebreak, two points from the set.

But Paul dumped the second serve return into the net after Sinner went right at the body. At the next point at 5-5, Sinner jammed Paul, knowing that he takes the backhand return early, which the American sailed wide.

At 6-5, Sinner crunched a crosscourt forehand which Paul couldn’t handle, giving Sinner the set.

Sinner is up two sets to love on Paul, inching closer to the quarterfinal.
