Meanwhile, Sabalenka, who turned 25 on Friday, picked up her second Madrid trophy in three years with a powerful 6-3, 3-6, 6-3 upset of world No.1 Iga Swiatek in the final on Saturday.
Here’s a look at some of the highlights from an eventful fortnight in Madrid.
Welcome to the Carlitos Show
Alcaraz is a big match player and he knows it. The young man from Murcia is now 10-3 in career finals and 4-0 in title deciders at the Masters 1000 level.
He joked with reporters in Madrid that he wished he could stay a teenager a little longer “for the statistics”. Indeed, his list of records set as a teenager is both long and impressive.
Against the big-serving Struff in the final on Sunday, Alcaraz lost the second set as the German adopted an all-out attack strategy, serving-and-volleying at every opportunity. Alcaraz hit the reset button in the deciding set though to extend his current winning streak to 11 straight matches.
