San Jose, California: Denis Istomin capitalized on all five break point chances as he advanced to the ATP Tour's SAP Open quarter-finals with a 6-3, 6-7 (5/7), 6-2 win over Benjamin Becker on Thursday.
The sixth seeded Istomin, who finished runner-up in the event last year, needed one hour and 49 minutes to continue his mastery over Germany's Becker. He has now beaten Becker in three of four career meetings.
The 26-year-old Uzbek has reached the quarter-finals in three tournaments this season, including at the Brisbane International where he lost in the quarter-finals to Andy Murray. He also made the final eight at a tournament in January in Sydney, Australia.
