WASHINGTON, Aug. 5 (Xinhua) -- Australia's Nick Kyrgios has blasted 18 aces to dispatch Russia's 10th-ranked Daniil Medvedev 7-6 (6), 7-6 (4), capturing the ATP Washington Open title Sunday.
The 24-year-old Aussie, who struggled through the opening set, claimed his sixth career ATP crown at the US Open tuneup event.
Kyrgios, 5-1 this year against top-10 rivals, won his second title of the season after Acapulco in March and jumps 25 positions to 27th in Monday's new rankings, his first top-30 appearance in 43 weeks.
Medvedev, 23, was broken only twice this week but lost his lone sets to Kyrgios. He has equalled his career-best ranking of ninth.
Kyrgios, who beat Medvedev on Rome clay in May in their only prior meeting, would face him again in the second round next week at Montreal if Kyrgios beats Britain's Kyle Edmund.
American Jessica Pegula captured her first WTA singles title by crushing Italy's Camila Giorgi 6-2, 6-2 in the WTA Washington Open final.
Pegula's only other WTA singles final was last September at Quebec City, where she lost to France's Pauline Parmentier.
Pegula, who jumps 25 spots to a career-best 54th on Monday's rankings, broke early in each set and closed matters just inside an hour with an ace.
