Coco Gauff fought back from a set down to beat her fellow American Jessica Pegula 4-6, 6-3, 6-3 on Tuesday, overcoming an error-strewn start to reach the Wimbledon semi-finals for the first time.
After appearing on course for defeat against the in-form fourth seed with four double faults and 17 unforced errors in the opening set, Gauff raised the level of her groundstrokes, producing just three more double faults and only 15 unforced errors across the final two sets.
