Britain’s Cameron Norrie earned a notable scalp by beating Bulgarian ninth seed Grigor Dimitrov to reach the Miami Open third round for the first time in his career.
Norrie won 7-5 7-5 against Dimitrov – who reached last month’s Australian Open quarter-finals – to claim a second win over a top-20 opponent this season.
“It is a massive win for me and I will take a lot out of it,” said Norrie, 25.
British number one Dan Evans lost to American Frances Tiafoe.
The 19th seed was beaten 6-7 (5-7) 6-3 6-3 by Tiafoe, who will face Dusan Lajovic, seeded 16th, in the last 32.
Meanwhile, fellow Briton Katie Boulter lost in the WTA event.
Norrie reached the last 32 after the world number 56 outplayed and outlasted Dimitrov to continue his fine start to the 2021 season.
