World No. 2 Carlos Alcaraz withdraws from ATP tournament in Rio.
The 20-year-old suffered an ankle injury during the first round. Thiago Monteiro, winner by forfeit, was also concerned about his condition. The Spaniard hopes to be restored for the exhibition match against Rafael Nadal, organized on March 4 in Las Vegas by Netflix. He was eliminated in the quarter-final of the Australian Open in January and in the semi-finals of the Buenos Aires tournament last week.
