The Big Three in men's tennis: Roger Federer, Rafael Nadal and Novak Djokovic

Roger Federer (20), Rafael Nadal (18) and Novak Djokovic (16) are the men's all-time leaders in Grand Slam singles titles. Not only that, but they have won every Grand Slam championship since the beginning of the 2017 season — four by Djokovic, age 32, and Nadal, 33, and three by Federer, 38. They can make it 12 in a row if one of them wins the U.S. Open. The last time someone outside the Big Three won a major singles title was Stan Wawrinka at the 2016 U.S. Open.
