Playing under pressure was Friday's doubles theme at the Cincinnati Open, where Jamie Murray and Ivan Dodig dispatched fifth-seeded Italians Simone Bolelli and Andrea Vavassori in a tight 7-5, 7-6(4) contest while three other matches went to a Match Tie-break.
Murray and Dodig are into the last eight and will next face Arthur Fils and Nicolas Jarry.
American wild cards Mackenzie McDonald and Alex Michelsen became the first team to reach the semi-finals after they saved two match points to upset the 2022 titlists Rajeev Ram and Joe Salisbury 6-3, 5-7, 11-9. The third seeds held two consecutive match points on serve at 9/7 in the Match Tie-break before McDonald and Michelsen tallied four consecutive points.
Top seeds Marcel Granollers and Horacio Zeballos, who won Montreal last week, defeated Hugo Nys and Jan Zielinski 6-7(3), 6-4, 10-6. Seventh seeds Harri Heliovaara and Henry Patten, fifth in the PIF ATP Live Doubles Race To Turin, survived Wesley Koolhof and Mate Pavic 6-7(3), 7-6(5), 10-5.
