Aryna Sabalenka put on a serving masterclass to crush American Coco Gauff 6-4, 6-0 on Wednesday and reach the semi-finals at Indian Wells, where she will face seventh seed Maria Sakkari.

The Australian Open champion never faced a break point and used her hard and accurate serve to dispatch Gauff.

Sabalenka appears to have put her past struggles with double faults firmly behind her, not committing a single one against Gauff, while pounding down five aces.

Gauff quickly fell 2-0 down in the first set and was unable to match the Belarusian’s level de - spite playing well. Sabalenka kept her foot on the gas to dominate the second set despite the California crowd’s attempts to urge on the sixth-seeded Gauff.

Later on Wednesday, Greek Sakkari fought back from a set down to beat 15th-seeded Czech Petra Kvitova 4-6 7-5 6-1. Among men, Frances Tiafoe beat Britain’s Cameron Norrie 6-4, 6-4 to reach his first Masters 1000 semi-final where he will face Daniil Medvedev who dispatched Spaniard Alejandro Davidovich Fokina 6-3, 7-5.
