NEW YORK — Top-ranked Jannik Sinner finished off a 7-5, 7-6 (3), 6-2 victory over Jack Draper to reach his first final at the US Open — and second at a Grand Slam tournament his year — after they simultaneously received treatment from trainers on a humid afternoon Friday.

Sinner, a 23-year-old from Italy who was exonerated in a doping case less than a week before the tournament began, needed his left wrist massaged at a changeover after falling during a point he managed to win late in the second set.

During the same break in the action, the 25th-seeded Draper, a 22-year-old from Britain, got medical attention after vomiting twice on the court between points.

While both competitors were being looked at, a vacuum was being used to clean up the green ground behind the baseline where Draper had thrown up. It was, to say the least, an unusual scene at Arthur Ashe Stadium, where the temperature was in the high 70s and the humidity was above 60%.

Sinner, the first Italian man in tennis history to reach the US Open singles final, awaits the winner of the all-American semifinal between Taylor Fritz and Frances Tiafoe later Friday.

Sinner, who won the Australian Open in January, is looking to become the third man in the Open era to win his first two major titles in the same calendar year. He would join Jimmy Connors, who won his first three major titles in 1974, and Guillermo Vilas in 1977.
