Argentina’s Diego Schwartzman demolished top seed Bernard Tomic 6-2, 6-2 to reach the TEB BNP Paribas Istanbul Open quarter-finals. He’ll next face Damir Dzumhur.

Diego Schwartzman, who left Istanbul last year with unforgettable memories, scored a stunning upset against top seed Bernard Tomic in the second round. World no.87 from Argentina dropped only four games as he advanced to last eight in 63 minutes.

Playing his first and only semi-final of his career at the 2015 TEB BNP Paribas Istanbul Open, where he also forced Roger Federer to a final set, was off to a flying start as he took 3-0 lead before completing the first set 6-2.

Currently ranked 22nd Tomic tried to change the ways in the second. He broke serve in the second game, but from that moment it was all Schwartzman. 23-year-old won six consecutive games to earn his first-ever Top-25 win with 6-2, 6-2.

Schwartzman will next meet coeval Damir Dzumhur in the quarterfinals. Following his win over 7th seed Teymuraz Gabashvili, Bosnian trailblazer Dzumhur knocked out Illya Marchenko 6-3, 5-7, 6-3 in 2 hours and 14 minutes in the opening encounter of the day.

It will be maiden quarterfinal this season for both Schwartzman and Dzumhur, also first-time meeting between two players.
