Carlos Alcaraz beat Matteo Arnaldi 6-7(6), 6-0 and 6-1 in the first round of the Indian Wells tournament. The 20-year-old Spaniard is defending his title but has not won since Wimbledon in July.

He is still recovering from an ankle injury he suffered in Rio de Janeiro two weeks ago. The world number two has won 13 matches without letting up - and could lose from the second step of the list if he does not win.
