Top seed Alexander Zverev (27) achieved a personal benchmark and advanced to the quarter-finals of the Erste Bank Open with a 6-2, 7-5 defeat of Marcos Giron (31) on Wednesday in Vienna, Austria.

Zverev struck 10 aces and converted all three break chances in the 73-minute match for his 61st singles win of the season, eclipsing the German’s career high set in 2018. His next match is against sixth-seeded Italian Lorenzo Musetti, who advanced in a walkover when France’s Gael Monfils withdrew due to illness.

Italy’s Matteo Berrettini also moved into the last eight with a marathon 6-3, 6-7(6), 6-3 victory over fifth-seeded Frances Tiafoe in 3 hours and 3 minutes. In first-round matches, No. 3 seed Grigor Dmitrov of Bulgaria beat China’s Zhizhen Zhang 6-4, 7-5 and Brandon Nakashima eliminated No. 4 Tommy Paul 6-4, 6-4.
