French wild-card entry Lois Boisson upset Mirra Andreeva in front of a boisterous crowd to reach the semifinals of the French Open.

Coco Gauff dropped the first set, but leaned on stellar range and sharp anticipation to edge fellow Madison Keys in an error-clogged All-American meeting Wednesday to reach her third French Open semifinal in four years.

Coco Gauff overcame 10 double-faults and the first set she’s dropped in the tournament to beat Madison Keys 6-7 (6), 6-4, 6-1 at the French Open and reach the semifinals for the third time.
