British number three Cameron Norrie is into the quarter-finals of the Delray Beach Open in Florida, following a straight sets win over third seed Adrian Mannarino.
The world number 74 continued his build-up to next week’s Australian Open by beating the Frenchman 6-2, 7-5 to set-up a last eight meeting with American Frances Tiafoe.
Norrie made a rapid start to the tie, breaking in his opponent’s first two service games and then again at 5-2 to rap up the first set inside 37 minutes.
