British number one Cam Norrie asserted his seniority over Jack Draper in the Miami Open second round, but not before being made to work hard.

Draper’s promise was clearly in evidence throughout a narrow 7-6 6-4 defeat in this mini Battle of the Brits, suggesting his rise will take him into the top 100 before the summer is out.

Faced with the 20 year-old left-hander from Surrey, world number 12 Norrie only edged the tiebreak 7-5 and could have gone behind in the second set, but survived to meet either John Isner or Frenchman Hugo Gaston.

With Draper displaying both power from the baseline and some neat dropshots around the net, he came back from 2-5 in the first set. In the second he had chances to take an early lead but found his fellow southpaw ultimately too consistent.

Draper is currently ranked 146 after winning three Challenger titles already this season. He played to a level well above that and, given a further run of full fitness, is sure to continue his progress this year.

On Saturday Andy Murray takes on world number two Daniil Medvedev, with Ivan Lendl in attendance for the first time since his reappointment as the Scot’s coach.

The twice Wimbleton champion is looking forward to the challenge, saying: ‚I spent a few days with Ivan this week and it was good. We worked on some stuff, not loads will change in a few days but I feel a lot more clear about what it is I am trying to do and what I will be working on in this next period.

‚I have a lot of trust in what he is telling me because of how we did the last couple of times. (British coach) Mark Hilton has also been fantastic for me, very positive and professional. He has helped me a lot with my mindset.

‚I’m in a good place right now. I know what I want to work on and improve but maybe Ivan will see smaller things and look at the data and find something we haven’t been seeing.‘
