Madison Keys scored a come-from-behind victory over third-seeded Coco Gauff on Friday to advance to her first tournament final in two years at the Adelaide International 2 in Adelaide, Australia.
In a matchup of Americans, Keys, 26, beat the 17-year-old Gauff 3-6, 6-2, 7-5 to set up a final against another American, Alison Riske.
Serving at 5-6 in the final set, Gauff was broken by Keys in the final game. Keys forced 17 break points in the match, converting four of them.
Earlier Friday, Riske, 31, advanced when fourth-seeded Tamara Zidansek of Slovenia withdrew ahead of their semifinal due to an abdominal injury.
Keys has won five of the six meetings with Riske. They haven't faced each other since the first round of the 2016 U.S. Open, which Keys won 4-6, 7-6 (5), 6-2.
