Sloane Stephens fought back from a set down to reach her first hard court semi-finals since 2018 as she defeated Daria Saville at the WTA Abierto Zapopan on Friday.

The 2017 US Open champion triumphed in two hours and 29 minutes over the Australian, winning 4-6 6-3 6-2 in Guadalajara.

Stephens, who will play Russian Anna Kalinskaya in the last four, had not reached a hard court semi since the 2018 WTA Finals.

But the American was forced to do it the hard way after losing the first set, saving nine of 13 break points across the match, with her ability to win second serve points proving key.

Colombian fourth seed Camila Osorio was bundled out in 80 minutes by Kalinskaya 6-4 6-1.

There was also a straight-sets win for Marie Bouzkova after she defeated third seed Sara Sorribes Tormo 6-4 6-1.

She will face Wang Qiang in the last eight, who proved too good for Slovakian Anna Karolina Schmiedlova 6-2 6-3.
