Cameron Norrie eliminated from Miami Open by Casper Ruud

British number one Cameron Norrie saw his run at the Miami Open ended by Norway's Casper Ruud in straight sets in Tuesday's fourth-round clash.

The 26-year-old was seemingly dealing with a calf problem throughout the contest and went down 3-6 4-6 to Ruud, who was handed a slight scare before finishing with a flourish.

With Norrie not at peak physical fitness, Ruud earned the early break for 3-1 in the fourth game of the first set, with frustrations boiling over for Norrie as he smashed his racquet on the court.

Ruud found himself serving for the match at 5-2 after another two breaks, but Norrie became the first player to break the Norwegian's serve in the tournament before holding to make things interesting at 5-4.

However, Ruud made no mistake in his next service game, as despite losing two match points, the 23-year-old booked his spot in the quarter-finals with his seventh ace of the day.

Ruud will now face the winner of the last-16 clash between number two seed Alexander Zverev and Australian qualifier Athanasios Kokkinakis, with Norrie aiming to shake off his calf issue before the clay court season begins next month.
