LONDON (Reuters) -World number one Aryna Sabalenka continues her quest for a first Wimbledon title when she takes on Elise Mertens, while two-times defending champion Carlos Alcaraz faces Andrey Rublev when the fourth round begins on Sunday.

Alcaraz's tennis is so often a highlight reel but on grass, he does his most devastating work in the negative spaces of points.

Unlike his top rival Jannik Sinner – who conceded just 17 games to his opponents in the first three rounds of Wimbledon and did not lose a single set – Carlos Alcaraz has not had a perfect run so far and has had to struggle more than expected to enter the second week.
