As the old faces begin to wash away and we are greeted with young, new prospects on the men's tour, we begin to see some parallels to the past. As of now, the predominant emerging rivalry is Sinner-Alcaraz. With Sinner, we have an ultra-consistent baseliner with a rally ball possessing enough power and margin to dictate rallies against even the most proficient. He is a capable volleyer, but doesn't come to net often. With Alcaraz, we have an exciting all-court talent. His game thrives on variety and shotmaking, whether it be volleys, drop shots, that weird forehand push slice thing, or his beautiful forehand that can end a point in one fell swoop. Although they obviously aren't perfect matches, the dynamics in the matchup seem to be similar to Djokovic-Federer. A consistent aggressive baseliner vs. An All-court maestro. Unfortunately with Djokovic vs. Federer, we were unable to see them compete prime for prime, and as such we were never really able to gauge who the better player was. It seems that taking the outcome of this upcoming Alcaraz-Sinner rivalry, with Alcaraz as A Federer-Proxy and Sinner as a Djokovic-Proxy, and extrapolating conclusions from that will be a great tool for tennis historians and fans alike.
