Novak Djokovic cruised into the quarter-finals of the Miami Open on Tuesday with a 6-2, 6-2 win over Italian Lorenzo Musetti in one hour 22 minutes.

Musetti, the 15th seed from Tuscany, got off to a flying start to take a 2-0 lead in the first set but then proceeded to lose the next nine games as the Serb, looking confident and sharp, ran away with the game.

Djokovic has won the Miami Open on six occasions but has not featured in the quarters since his last victory here in 2016.

The 37-year-old is now just three wins away from winning his IOOth tour-level title.

Djokovic will face American Sebastian Korda on Wednesday for a place in the semi-finals after the 24th seed beat French veteran Gael Monfils 6-4, 2-6, 6-4 in a rain-affected match.

Kordavisibly struggled with his wrist, however, and said after the match that he had been in discomfort with an injury that has caused him trouble in the past.

Korda later pulled out of his doubles match with partner Jordan Thompson.

Argentine Francisco Cerundolo upset fifth-seed Casper Ruud 6-4, 6-2 to take his place in the last eight.

Cerundolo, who enjoys plenty of support from South Florida's large Argentine community, has now reached the last eight in three of his past four appearances at Miami.
