Emma Raducanu displayed a combination of ruthlessness, grit and determination in a “very difficult” contest as Great Britain ousted reigning champions Canada to reach the semi-finals of the Billie Jean King Cup.

Emma Raducanu gave Great Britain a 1-0 lead over Canada in the quarter-finals of the Billie Jean King Cup as she defeated Rebecca Marino.

World No.103 Merino has never won a WTA title or got beyond the third round in a Major. And there was even a different sound to the shots off her racquet compared to the former US Open champion. Raducanu also made her run to every corner of the court.
