Hard pressed by a sometimes brilliant performance from 6'6" Medvedev......who is also lightning fast across the court, Nadal found the answers. One of which was a sliced backhand up the the line. Medvedev was creaming Nadal's usually potent top spin shots, much as Robin Söderling did famously at the French in 09. His biggest top spinners were right in Medvedev's hitting zone.
Still with a bit of guile, a bit of luck a bit of gamesmanship that Federer wouldn't have stooped to......Nadal prevailed. So we now have to go back more than 3 years to Novak Djokovic's win in the 2016 French to find a Major men's champion under 30.
If a game like tennis with it's severe physical challenges can produce 30 plus dominance.....we need to cherish our rugby veterans.
