In an all-German clash on the Pista Central, the #NextGen player beat qualifier Jan-Lennard Struff in straight sets 6-4, 6-3.
Zverev will celebrate his 19th birthday on Wednesday when he will take on Brazil’s World No. 35 Thomaz Bellucci.
This year, the young German has already defeated three top 20 players with Gilles Simon (twice) and US Open champion Marin Cilic.
