Two-time defending Wimbledon tennis champion Carlos Alcaraz looks to take his next step toward a three-peat with a fourth-round match against No. 14 Andrey Rublev Sunday on Centre Court.

Alcaraz’s unseeded opponent was ranked 125th in the world and was competing in the Wimbledon third round for the fourth time, having never gone beyond. The Spaniard ensured the wait continues for the 35-year-old, who was a 2018 Australian Open doubles semi-finalist.
