Djokovic marches into Miami quarters as Zheng exits

MIAMI GARDENS, Florida — Novak Djokovic cruised into the quarterfinals 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.
