Gauff plays right Keys on way to semis

All-American battle goes the distance with second seed to meet Boisson next

- 

Coco Gauff battled back from a set down to beat Australian Open champion Madison Keys in an error-strewn quarter-final at Roland Garros yesterday.

The second seed battled past her fellow American 6-7 (6/8), 6-4, 6-1 in a tense last-eight clash littered with a whopping 14 double-faults and 101 unforced errors.

Gauff will face world number 361 Lois Boisson, who upset Mirra Andreeva 7-6 (8/6), 6-3, for a place in her second French Open final today.

"It means a lot, especially getting through this tough match today, it wasn’t an easy match and I’m very happy to get through it,” she said.
