Cameron Norrie suffered a shock defeat in the second round of the Miami Open when he was beaten in straight sets by France’s Gregoire Barrere.
The British No 1 has enjoyed his visits to Miami in recent years, with the 27-year-old winning the title in 2021 and reaching the quarter-finals last year.
But he was dominated by Barrere on Saturday, with the world No 65 securing a 6-3 6-2 victory in an hour and 10 minutes.
After trading early holds, Barrere was able to strike first by breaking Norrie’s serve in the eighth game and the Briton could only offer mild resistance, with the Frenchman cruising home to set up a third-round meeting with Christopher Eubanks.
The American qualifier recorded the biggest win of his career so far as the world No 119 knocked out 17th-seeded Croatian Borna Coric 3-6 6-4 6-2.
Evans losing streak continues
Meanwhile, British No 2 Dan Evans saw his losing streak extend to six matches after Italian Lorenzo Sonego came from behind to win 4-6 6-3 6-2 in two-and-a-half hours.
Evans had started brightly, securing an early break in the first game and then held to lead 2-0 before closing out the first set.
However, the Italian world No 59 rallied to break Evans in the fourth game of the second set before maintaining a vital hold in the next game which allowed him to level the match.
The momentum remained with the Italian, who broke twice in the deciding set as he opened up a 4-0 lead and never looked like allowing Evans back into the match.
