Novak Djokovic rejoins Roger Federer, Rafael Nadal in Big 3

What had gone from a Big 4 to a Big 2 is now back to a Big 3, with Novak Djokovic rejoining Roger Federer and Rafael Nadal at the top of men's tennis. Each has been written off at some point. And each has won a major tournament in 2018: Djokovic's title at Wimbledon on Sunday, Nadal's at the French Open in June, and Roger Federer's at the Australian Open in January. Maybe the U.S. Open, which starts in 1½ months, will break the tie for season supremacy. That trio has combined to win 10 of the past 14 championships at Flushing Meadows: Five for Federer, three for Nadal, two for Djokovic. At least one, and sometimes two, appeared in 13 of the finals in that span. Federer, who turns 37 on August 8, won that event every year from 2004-08 but not since. Nadal, 32, is the reigning champion. Djokovic, 31, sat out the U.S. Open while missing the last half of 2017 because of an injured right elbow that he eventually had surgery on. (Video: SNTV).
