Koolhof/Tsitsipas Stun Second Seeds In Miami

Wesley Koolhof and Stefanos Tsitsipas produced the upset of the doubles tournament at the Miami Open presented by Itau. The Dutch-Greek tandem stunned second seeds Jamie Murray and Bruno Soares 6-3, 4-6, 10-7 on Sunday afternoon on Court 6.

Competing in their second tournament together, they had dropped a tight opener to top seeds Lukasz Kubot and Marcelo Melo in Indian Wells. But Koolhof and Tsitsipas found their chemistry in a flash in Miami, following a straight-set win over Karen Khachanov and Daniil Medvedev with the dismissal of the second seeds.

Koolhof and Tsitsipas will next face John Isner and Sam Querrey in the quarter-finals, after the Americans rallied past Rajeev Ram and Joe Salisbury 5-7, 7-6(2), 10-7. The duo has reached three ATP Masters 1000 finals together and clinched the title in Rome in 2011.

Elsewhere, Maximo Gonzalez and Horacio Zeballos stunned 2014 finalists Juan Sebastian Cabal and Robert Farah 6-4, 3-6, 10-7 to reach the quarter-finals. Zeballos has been a force on the doubles court this month, having lifted the BNP Paribas Open trophy with Nikola Mektic a week ago. He and countryman Gonzalez recently took the title in Buenos Aires after finishing runner-up in Cordoba.

In other action, Ivan Dodig and Edouard Roger-Vasselin set a meeting with Matwe Middelkoop and Diego Schwartzman, after the Croatian-French team defeated Marc Lopez and Feliciano Lopez 6-4, 6-3. Middelkoop and Schwartzman also progressed on Sunday, needing 65 minutes to dismiss sixth seeds Raven Klaasen and Michael Venus 6-4, 6-3.

Arguably the most efficient victory of the day was provided by Rohan Bopanna and Denis Shapovalov, who routed Marcel Granollers and Nikola Mektic 6-1, 6-2 in just 52 minutes. They could potentially face the five-time champions and third seeds Bob Bryan and Mike Bryan in the quarter-finals.
