Miami (USA): John Isner moved through into the Miami Open semi-finals after beating Novak Djokovic's conqueror Roberto Bautista Agut 7-6 (7-1), 7-6 (7-5) at the Hard Rock Stadium here on Wednesday.
The defending champion is yet to drop a set in Miami and powered down 24 aces in a match that lasted one hour and 45 minutes.
Interestingly, John is yet to lose a set at Hard Rock Stadium, ousting Sonego, Ramos-Vinolas, Kyle Edmund and Roberto Bautista Agut in eight tight sets
Both sets went to a tie-break but it was Isner who played some exquisite baseline shots at pivotal moments to move into the last four for the third time in Miami.
It will be the American's 12th ATP Masters 1000 semi-final, and he'll face either Felix Auger-Aliassime or Borna Coric of Croatia for a place in the final.
