The German Alexander Zverev, 5th in the world, was effective on Thursday to reach the semi-final of the Masters 1000 in Miami by beating the Hungarian Fabian Marozsan (57th) 6-3, 7-5. Completely in control, relying on a powerful first ball, the 26-year-old German, seeded number 4, took the lead in both sets.
Marozsan gave up his throw at key moments, at the start of the first set then by committing a double fault on the first set point obtained by his opponent. The 24-year-old Hungarian then recovered well, holding his opponent high as soon as the exchange lasted. But here again, the first match point was the right one for Zverev on Marozsan's serve in the 11th game of the second set.
The Hungarian should gain 19 places in the ATP rankings at the end of a tournament where he offered himself two top 10 players: the Dane Holger Rune (N.7) in the 2nd round and the Australian Alex De Minaur N.10 in eighth. Zverev will face the winner of the last quarter between the Spaniard Carlos Alcaraz, world number two, and the Bulgarian Grigor Dimitrov (N.12). The other semi-final will pit Italian Jannik Sinner (world No. 3) against Russian Daniil Medvedev (No. 4) on Friday.
