Defending champion Carlos Alcaraz dug in to avoid a shock loss against Emil Ruusuvuori and reach the third round of the Madrid Open.

The young Spaniard thrilled his home fans last year by defeating Novak Djokovic and Rafael Nadal on his way to the title, establishing himself as not just the future but the present of men’s tennis.
