Raducanu's second-round victory over Dayana Yastremska, who retired with illness, marked the first time the English player had recorded back-to-back victories since winning three games at Indian Wells 12 months ago.

The shock 2021 US Open champion made her return to the tour in January following an eight-month absence, during which she underwent operations on both of her wrists and had ankle surgery.

She said she was "not too concerned" about recent results - having won just three matches in the four tournaments she had played before Indian Wells - as the priority this year is to develop her game.

Testing herself against Sabalenka, who successfully defending her Australian Open title in January, Raducanu will be pleased with the progress she showed.

A single break of serve in the sixth game was enough for Sabalenka to take the first set, but only after Raducanu dismissed two set points on serve before putting her opponent under pressure with three break points as she served for the set.

Sabalenka moved a step closer to victory by claiming the first break five games into set two.

However, Raducanu produced an immediate response to stay in contention and continued to trouble the second seed by creating a break point after holding serve to lead 4-3.

Sabelenka struck what proved to be the decisive blow when she broke for a 6-5 lead, eventually serving out the contest with her fourth match point after Raducanu again missed three break points as she fought hard until the end.
