Hamburg, Germany (4E Sports) – Former junior World No. 1 Alexander Zverev continued his winning ways at the bet-at-home Open, beating 11th seed Santiago Giraldo, 6-4, 7-6(6), Thursday for a place in the quarterfinals.
“He’s a tough player and a really tough competitor,” said Zverev. “He got the break when I was serving at 5-4 and I just had to focus and play my game. Luckily, I got through in two sets.”
Zverev is the first 17 year old to reach the quarter-finals at an ATP World Tour 500 tournament since Rafael Nadal advanced to the last eight at the 2004 Dubai Duty Free Tennis Championships.
Zverev will next meet wild card Tobias Kamke, who reached his first ATP World Tour quarterfinal since September 2013 as he ousted fourth seed Alexandr Dolgopolov, 7-5, 2-6, 7-5.
The last 17 year old to reach the semi-finals or better at a tour-level event was when Marin Cilic — at 17 years 9 months — lost to Feliciano Lopez in the 2006 Crédit Agricole Suisse Open Gstaad semifinals.
Meanwhile, world No. 7 David Ferrer remains on course to capture his 22nd ATP World Tour title with a 6-3, 3-6, 6-3 victory over No. 16 Andreas Seppi.
Ferrer goes on to meet fellow Spaniard Pablo Andujar, who beat home favorite Dustin Brown 6-1, 6-2 in just 63 minutes.
Lukas Rosol saved all seven break points he faced to beat third seed Tommy Robredo, the 2006 champion, 7-5, 7-6(6) in one hour and 46 minutes. Rosol will play seventh seed Philipp Kohlschreiber, who beat No. 12 seed and 2011 titlist Gilles Simon 7-5, 6-3.
World No. 46 Leonardo Mayer reached his fourth ATP World Tour quarterfinal of the season as he defeated Dominic Thiem, 6-3, 6-2.
The 27-year-old Mayer goes on to face Serbia’s Dusan Lajovic, who was leading 3-1 when qualifier Filip Krajinovic was forced to retire due to illness.
On the women’s side, Roberta Vinci advanced to the quarterfinal of the Istanbul Cup after Alexandra Dulgheru retired Thursday. Vinci was leading, 6-3, 4-1, when the Romanian qualifier quit.
Next up for Vinci is Japan’s Kurumi Nara, who defeated Katerina Siniakova, 7-6 (7-5), 6-7 (3-7), 6-2.
Karolina Pliskova also booked a spot in the quarterfinal with a 6-2, 7-5 win over Israel’s Shahar Peer. Pliskova earned a quarterfinal matchup with top-seeded Caroline Wozniacki.
Ana Konjuh eliminated Misaki Doi, 6-4, 6-7 (3-7), 6-4, to seal a quarterfinal showdown against fourth seed Elina Svitolina.
In Bastad, Kaia Kanepi moved into the quarterfinal via a 6-3, 6-1 win over Richel Hogenkamp. She will next play Mona Barthel, who advanced with a 6-4, 3-6, 6-4 win over Gabriela Dabrowski.
Silvia Soler-Espinosa also advanced after beating Julia Goerges. She will next meet Alexandra Panova, a 6-2, 6-4 winner over American Grace Min.
