Not much of a change of guard when Nadal and Djokovic are playing their best tennis. Tsitsipas vs Federer was a coin flip. Somebody has to make the semifinals, a second guy has to when one of the Big3 loses in the 4th round... Tsitsipas is on the rise (along with Khachanov, Medvedev, Shapovalov and already established A. Zverev) and takes advantage of the downward swing for many second-tier players. We've discussed A. Murray (whom we'd have to call a first-tier player), but Wawrinka, Tsonga and Berdych are also returning from a long absence. Ferrer is about to retire, Goffin got a goofy injury, Del Potro is still ranked 4th, but has been up and down battling injuries for years. Raonic has missed some time. The bodies of Gasquet and Monfils can't play back to back weeks anymore. And then there's unpredictable guys like Dimitrov and Kyrgios.
