American No 4 seed beats Belinda Bencic 6-3, 1-6, 6-3 in quarter-final
Gauff next faces 13th seed Karolína Muchová for a place in final
Coco Gauff may be struggling with an unfamiliar arm injury, indifferent form and the pressure of attempting to transform her serve with the entire tennis world watching, but the one quality that will never evade her is her fighting spirit.
Under far from ideal circumstances, Gauff’s mental toughness continues to guide her through the Miami Open draw and to her best ever result at her hometown tournament. She navigated a path into the semi-finals for the first time in her career with an arduous 6-3, 1-6, 6-3 win over Bencic.
Although Gauff has not always been able to consistently produce her best level this year in Miami, and she has been taken to a final set in all four of her matches so far, she continues to find a way through.
