Ram/Salisbury Edge Kokkinakis/Kyrgios In Battle Of Reigning Grand Slam Champs

Rune/Tsitsipas down Wimbledon finalists Mektic/Pavic in Match Tie-break

In Thursday's matchup between the reigning US Open champions and the this year's Australian Open winners, the New York titlists emerged victorious at the Western & Southern Open.

Top seeds Rajeev Ram and Joe Salisbury edged the Australian duo of Thanasi Kokkinakis and Nick Kyrgios 6-7(3), 6-2, 10-8, claiming victory without dropping serve in Cincinnati. The American-British duo saved the only two break points they faced in the opening game of the match but still needed to claim a tight Match Tie-break to earn their first victory since reaching the Wimbledon semi-finals.

After dropping the first-set tie-break and dominating the second set with two breaks, Ram/Salisbury required three match points to seal the Match Tie-break as the Aussies threatened to come back from 6/9 down.

Behind a 91 per cent (41/45) win rate on first serve, the pair advanced to face Wednesday winners Karen Khachanov and Denis Shapovalov in the quarter-finals.

Holger Rune and Stefanos Tsitsipas also won a Match Tie-Break on Thursday, upsetting fifth seeds and Wimbledon finalists Nikola Mektic and Mate Pavic 6-7(5), 6-3, 10-7. The Danish/Greek team converted on three of seven break chances, including in the final game of set two, when a scrambling Tsitsipas lob brought up set point.

Rune/Tsitsipas will next face fourth seeds Marcelo Arevalo and Jean-Julien Rojer in the quarter-finals. The Salvadoran/Dutch team finished as 6-3, 7-6(11) winners after a marathon second-set tie-break against Americans William Blumberg and Steve Johnson.

Second seeds Marcel Granollers and Horacio Zeballos also advanced to the quarter-finals with a 6-3, 6-3 win against Grigor Dimitrov and Andrey Rublev, while sixth seeds Tim Puetz and Michael Venus survived a Match Tie-break to notch a 4-6, 7-6(2), 10-8 victory against Lloyd Glasspool and Harri Heliovaara.
