Venus Williams is through to the semi-finals of the US Open after beating Petra Kvitova in three sets at Flushing Meadows.
Williams came through 6-3 3-6 7-6 (7-2) and will now play compatriot Sloane Stephens, who beat Anastasija Sevastova also in three sets, 6-3 3-6 7-6 (7-4) to make last four.
With Madison Keys and Coco Vandeweghe also through to the last eight, there is the prospect of an all-American semi-final line-up, but at least one American is now guaranteed to be in the final.
As for Stephens, she has only just returned to action following an 11-month lay-off with a foot injury, and could not hide her emotions after the win.
"Oh man, I'm getting teary-eyed," said Stephens. "I think my coach is probably crying. This is just incredible. When I started my comeback at Wimbledon I could never have dreamed of this happening. Making the semi-final of my home Slam, it's indescribable.
"I just told myself to keep fighting. I'd been playing so well and so consistent, I knew if I stuck with it I'd have a chance, and that's what I did."
