INDIAN WELLS (AFP) — World No. 1 Iga Swiatek overpowered Marta Kostyuk 6-2, 6-1 to reach the final at the ATP-WTA Indian Wells Masters.

Four-time Grand Slam champion Swiatek, who won the 2022 Indian Wells title, needed just 69 minutes to get past 32nd-ranked Ukrainian Kostyuk and will face either US Open champion Coco Gauff or Maria Sakkari of Greece in Sunday's final.

Meanwhile, Maria Sakkari suppressed a late surge from Coco Gauff, holding off the US Open champion 6-4, 6-7 (5/7), 6-2 to book a title showdown with Swiatek.

In a match halted twice by rain, Greece's Sakkari squandered three match points in the second set but pulled away in the third to reach the Indian Wells final for the second time in three years. She fell to Swiatek in the title match in 2022.

Swiatek and Kostyuk avoided the desert showers, but played in overcast, chilly conditions that did nothing to slow the red-hot Swiatek.

"I think it was the cleanest match I played here," said Swiatek, who hit 14 winners with just six unforced errors and didn't face a break point.

"I didn't really have any moment today in the match where I didn't feel confident."

"I have all the positive vibes."

Although she has reached the final without dropping a set, Swiatek had insisted after prior victories that she had a few things in her game to sort out.

It looked as if she had done just that as she put Kostyuk on the run early, piling on the pressure with her precision and power.

The Ukrainian, playing in her first 1000 level semifinal, held serve to open the match, but Swiatek won the next five games and pocketed the opening set in half an hour.

Kostyuk, who finished with 17 winners and 23 unforced errors, could find no way to right the ship.

She fell behind 3-0 in the second set and required treatment on her left foot apparently after jamming it during a point.
