Medvedev, who defeated Djokovic at the 2021 US Open and stalled his progress to the calendar Grand Slam, had claimed the title last year with a perfect 5-0 record, including a historic hat-trick of wins over the world's Top-3 players -- Djokovic, Spain's Rafael Nadal and Dominic Thiem of Austria -- a first in the 50-year history of the event.
The groupings were announced on Thursday night at the tournament draw ceremony here.
