PARIS — It is surely time for a new favorite number for Rafael Nadal.
Once a very promising soccer player, he has long been partial to No. 9, which often denotes a striker, but it is the No. 10 that has kept bringing him joy and fulfillment this spring.
Nadal had already won a record 10th singles title on the clay in Monte Carlo and in Barcelona. On Sunday, to no one’s surprise, he did the same at the clay-court event that still matters most, defeating Stan Wawrinka, 6-2, 6-3, 6-1, for his 10th French Open crown.
