Miami Open: Norrie defeats Dimitrov, Evans and Boulter knocked out

British number two Cameron Norrie pulled off a superb straight-sets win over Grigor Dimitrov at the Miami Open.

Norrie won four games in a row to come from behind to win the first set against the world number 16.

The pair shared breaks early in the second but Norrie broke to love before serving out the match to win 7-5 7-5.

It was worse news for 19th seed Dan Evans, who went down in three sets to USA’s Frances Tiafoe.

Evans took the first set in a tie-break but lost four successive games as Tiafoe leveled.

It was the world number 58 who broke clear in the decider to knock win 6-7 6-3 6-3.

In the ladies draw, Katie Boulter’s Miami journey came to an end at the hands of world number 16 Elise Mertens.

The world number 319 had surpassed expectations by getting this far, and for a short period at the start of the match it looked like she could match Mertens.

Boulter took the opening three games but Mertens hit back to win the first set 6-4.

Mertens showed her superiority in the second set, winning six in a row to take it 6-1.
