NEW YORK (AP) — Novak Djokovic is 27-0 in Grand Slam matches in 2021. That means he is one victory from being the first man since Rod Laver in 1969 to win all four major tennis championships in one season. Djokovic is a 34-year-old from Serbia who is ranked No. 1. He won seven matches at the Australian Open, seven at the French Open and seven at Wimbledon to collect those trophies. Now he has added six wins at the U.S. Open as he heads into the final against Daniil Medvedev on Sunday. A title at Flushing Meadows also would give Djokovic 21 career majors, breaking a tie for the men’s record he shares with Roger Federer and Rafael Nadal.
