Sloane Stephens books Miami Open final clash with Jelena Ostapenko

Sloane Stephens will face Jelana Ostapenko in the Miami Open final after overcoming Victoria Azarenka.

The Belarusian former world number one and three-time Miami Open winner was given a wildcard into the tournament and had already seen off Karolina Pliskova, Agnieszka Radwanska and Anastasija Sevastova en route to the last four.

Azarenka took the first set 6-3, but four double faults in the second brought Stephens back into contention as Azarenka lost three consecutive service games.

Stephens then made short work of her opponent in the deciding set, taking it 6-1.

Jelena Ostapenko will be her final opponent after she comfortably beat qualifier Danielle Collins 7-6 (7/1) 6-3.

Collins, who conquered Venus Williams in the quarter-finals, met her match against the Latvian, who was ruthless in the first set tie-break breaking her four times as Ostapenko took the first set before cruising to victory on her first match point.
