Frances Tiafoe battled past Briton Dan Evans 3-6 7-5 6-3 to put the United States into the semi-finals of the United Cup mixed team tournament on Wednesday as Poland and Greece also advanced. The three countries who won their "city finals" to progress were joined in the last four by Italy, the runners-up with the best record in the $15 million event which replaced the short-lived ATP Cup to open the 2023 season.
