(Cincinnati) Coco Gauff created a surprise on Saturday by eliminating in the semi-finals of the WTA 1000 tournament in Cincinnati the world No.1, Iga Swiatek, in three sets 7-6 (7/2), 3-6, 6-4 .

The American won the first set in the tiebreaker not without passing three aces and winning 85.7% of the points on her first serve.

But Swiatek turned things around by winning the second 6-3. The Pole waited for the 4th game of this set to pass her first ace and then concluded on a white break to return to Gauff’s level.

In the last set, it was Gauff who broke to lead 4 games to 3 then 5 to 3 on his serve by multiplying the high balls to hinder his opponent.

The American, however, was nervous until the end with in particular a double fault while serving for the match, also letting slip two match points, before prevailing on an unforced error from the Pole.
