Coco Gauff defeated Russian teenager Mirra Andreeva in straight sets to march into the semi-finals of the Italian Open.
Gauff, who breezed past Britain's Emma Raducanu on Monday, continued her impressive run on clay with a 6-4 7-6 (7-5) victory against seventh seed Andreeva.
The 21-year-old American is now guaranteed to become the new number two in the world rankings, overtaking Iga Swiatek.
Gauff will face top seed Aryna Sabalenka, who beat her in the final of the Madrid Open this month, or China's Zheng Qinwen in the last four.
