Sort:  

Djokovic is really dominating right now, with Federer just out of yet another surgery and Nadal injured as well. But plenty of 'new names' (at least for me): Stefanos Tsitsipas, Daniil Medvedev, Alexander Zverev, and the young ones like Félix Auger-Aliassime from Quebec and the 18 year old Alcaraz who just lost in quarter-finals due to injury.
I don't watch very closely either, but I like to watch the long match summaries during the major tournaments
