Emma Raducanu was bundled out of the Miami Open in the first round by form US Open champion Bianca Andreescu in a three-set match that lasted two hours and 35 minutes on Wednesday.

The Briton, who won the US Open in 2021, went down 6-3 3-6 6-2 in a genuine tug-of-war against the 31st-ranked Canadian.

Andreescu sent down seven aces for the match, including four in the first set along with 12 winners as she claimed an early lead.

Raducanu responded with greater aggression, securing the crucial break in the eighth game, before serving out to level the contest.

But Andreescu showed composure and quality in the big points in the final set, winning the final four games to round out the victory, sealing a second-round clash with seventh seed Maria Sakkari.

Andreescu finished with 32 winners compared to Raducanu's 20, while the Briton committed 40 unforced errors.

World number 42 Shelby Rogers edged out USA compatriot Sloane Stephens in just under two hours, winning 6-4 3-6 6-2. Rogers will take on second seed Aryna Sabalenka, who is arguably the tournament favourite after top seed Iga Swiatek's withdrawal, in the next round.

Rogers was one of five Americans to progress, including 2020 Australian Open champion Sofia Kenin who defeated Australia's Storm Hunter 6-0 7-6 (7-5).

World number 35 Amanda Anisimova retired down 7-6 (7-5) 5-2 to countrywoman Madison Brengle.

Leylah Fernandez, the player whom Raducanu beat in the 2021 US Open final, advanced into the second round with a 6-4 6-3 victory over Lesia Tsurenko in 88 minutes.
