Daniil Medvedev is a Russian right-hander whose unorthodox, deep-court game — flat groundstrokes taken well behind the baseline, a two-handed backhand, and a serve delivered from an unusually tall, angular motion — has made him one of the hardest players on tour to play against. He won the US Open, ending a long run of near-misses in Grand Slam finals, and has held the world No. 1 ranking. Known for his sharp on-court personality and tactical intelligence, he remains one of the leading hard-court players of his generation.
