Sinner-2

NEW YORK — Top-ranked Jannik Sinner reached the US Open semifinals for the first time by getting past 2021 champion Daniil Medvedev 6-2, 1-6, 6-1, 6-4 on Wednesday night.

Sinner, who took over as the title favourite after Week 1 exits by Novak Djokovic and Carlos Alcaraz, is the only man remaining in the field with a Grand Slam trophy. He won his first at the Australian Open in January by beating Medvedev in the final in five sets after dropping the first two.

As reflected by the accurate-as-can-be score, this matchup was unusually topsy-turvy as they took turns dominating a set at a time. First, it was Sinner who was superior. Then that role was played Medvedev. Then Sinner regained the upper hand in the third. In the fourth, from 3-all, Sinner surged, saving a pair of break points, then breaking Medvedev to lead 5-3.

Sinner — a 23-year-old from Italy who was cleared in a doping case less than a week before the US Open started after testing positive twice for trace amounts of an anabolic steroid in March — will go up against No. 25 Jack Draper of Britain on Friday for a berth in the title match.

That day’s other semifinal will be No. 12 Taylor Fritz vs. No. 20 Frances Tiafoe in the first all-American men’s matchup at this stage at a major in 19 years.

The women’s semifinals Thursday night are Jessica Pegula vs. Karolina Muchova, and Aryna Sabalenka vs. Emma Navarro. Pegula eliminated No. 1 Iga Swiatek 6-2, 6-4 on Wednesday.

The 22-year-old Draper reached his first Grand Slam semifinal — and became the first British man to get that far at Flushing Meadows since Andy Murray won the 2012 trophy — by overwhelming No. 10 Alex de Minaur 6-3, 7-5, 6-2.

Draper has won all 15 sets he’s played so far, but things figure to get tougher against Sinner.

“This is not kind of like an overnight thing for me. I’ve believed for a long time that I’ve been putting in the work and doing the right things, and I knew that my time would come,” said Draper, whose upper right leg was taped by a trainer after he felt something at the end of the first set. “I didn’t know when it would be, but hopefully from here, I can do a lot of amazing things. I’m very proud of myself.”
