Tiafoe rallies past Evans to clinch U.S. win vs. Great Britain in United Cup city final

The U.S. United Cup team is moving on to a semifinal date with Poland after beating Great Britain 4-1 in the Sydney city final.

A perfect day by the U.S. women, behind the efforts of Madison Keys and Jessica Pegula, and a clinching come-from-behind win from Frances Tiafoe helped secure the Americans' berth in the next round.

"It was a great day," U.S. captain David Witt said. "They went out and fought hard. Everybody got it done. Played some great mixed doubles. Jess played great. Frances had a battle. It was a good day."

Two three-setters had the teams even early on. Keys rallied from a set down to beat Katie Swan 2-6, 6-3, 6-4 in the opening match, but Taylor Fritz lost to Cameron Norrie 6-4, 5-7, 6-4, despite having a break lead in the decider.  

"I came out not playing super well and found a way to get into the match," Keys said. "I don't think I ever really found my top level, but I figured it out and I started playing a lot smarter and managed to get it done."

But dominance by Pegula—6-2, 6-0 against Harriet Dart in 57 minutes—put the U.S. back on top, and gave the team a lead it wouldn't relinquish. 

"I think I did everything really well today. I could feel it," Pegula said. "Some days you come out firing and you feel really good. I was honestly trying to settle myself down because I was seeing the ball really well today."
