German fourth seed Alexander Zverev moved into the Miami Open semi-finals with a dominant win which ended the run of Hungary's Fabian Marozsan.
Zverev, 26, won 6-3 7-5 to reach the last four at the event for the first time since 2018.
The Olympic champion used his serve to great effect, while taking four of the seven break points he created against 57th-ranked Marozsan.
Zverev will play Spain's Carlos Alcaraz or Bulgaria's Grigor Dimitrov next.
Top seed Alcaraz and Dimitrov, seeded 11th, play their quarter-final match in Thursday's night session at the Florida event.
