Daniil Medvedev's sore right ankle wasn't a factor Wednesday as he beat Alejandro Davidovich Fokina 6-3, 7-5 to reach the semi-finals at Indian Wells, where Aryna Sabalenka and Frances Tiafoe raced into the final four.

Medvedev showed little ill effect from the twisted ankle he suffered in a three-set battle against Alexander Zverev a day earlier as he pushed his ATP match winning streak to 18 straight.

He booked a semi-final clash with 16th-ranked American Tiafoe, who beat 2021 Indian Wells winner Cameron Norrie 6-4, 6-4.

Australian Open champion Sabalenka, still building on her maiden Grand Slam title in Melbourne, overpowered Coco Gauff 6-4, 6-0 to advance at the combined WTA and ATP Masters 1000 event.
