Coco Gauff is through to the semi-finals of the China Open for a second consecutive year after coming from behind to beat Yuliia Starodubtseva.
Fourth seed Gauff lost the first set of the quarter-final on Thursday but fought back to beat the Ukrainian qualifier 2-6 6-2 6-2.
The American - ranked sixth in the world - has had a difficult year having failed to reach a Grand Slam final and losing in the third round of the Paris Olympics.
Gauff, 20, will face 15th seed Paula Badosa in Saturday's semi-final for a spot in her first final since winning in Auckland in January.
