Coco Gauff, 18, the youngest finalist at Roland Garros in two decades, whose striking sensibleness puts her sunshine smile to shade, will take on the rampaging world No.1 Iga Swiatek for the Coupe Suzanne Lenglen. Swiatek, 21, extended her winning streak to 34 matches in stopping the charge of Daria Kasatkina 6-2, 6-1 in the semifinals, the result leaving her one short of Venus Williams' 21st century record for successive wins. Gauff, who had 14 winners in her 98-minute 6-3, 6-1last-four win over Italian Martina Trevisan, however, struck her firmest blow on Court Philippe Chatrier during her on-court interaction, reminding fans yet again that she was more than a tennis sensation.
