Granollers/Zeballos Upset Top Seeds Koolhof/Skupski In Roland Garros QFs

Dodig/Krajicek down Krawietz/Puetz

Marcel Granollers and Horacio Zeballos continued to march through the Roland Garros doubles draw with an upset of top seeds Wesley Koolhof and Neal Skupski on Tuesday in Paris.

The 10th seeds have not dropped a set in the tournament, and they carried their strong form into the quarter-finals with a 6-3, 7-6(4) win against Koolhof/Skupski on Court Simonne-Mathieu. The Spanish-Argentine duo saved the only break point they faced and won 85 per cent of their first-serve points in the victory while converting on one of their two break chances.

Granollers/Zeballos had not lost more than three games in a set this fortnight until they were pushed to a tie-break by the top seeds, but a strong finish ensured their perfect set record remained intact.

They will next meet fourth seeds Ivan Dodig and Austin Krajicek in Thursday's semi-finals, after the fourth seeds moved past 11th-seeded Germans Kevin Krawietz and Tim Puetz 7-6(6), 5-7, 6-4. Dodig/Krajicek, who notched three of their four Roland Garros wins in a deciding set, secured the win despite converting on just one of nine break points on Court Suzanne-Lenglen.

Thursday's other men's doubles semi-final will see 12th seeds Matwe Middelkoop and Andreas Mies take on Belgians Sander Gille and Joran Vliegen. Both teams advanced with Monday quarter-final wins.
