Murray and del Potro suffer exits

Top seed Juan Martin del Potro and No. 2 Andy Murray were both knocked out of the Rotterdam World Tennis in quarter-final upsets on Friday by similar 6-3, 6-4 scorelines.

Latvian Ernests Gulbis ended del Potro's winning run when he beat the top seed, while unseeded Croatian Marin Cilic won his eighth match in a row this season with Murray his latest victim.

Third seed Tomas Berdych maintained the seeded status quo with his 6-7 (9/11), 6-2, 6-4 comeback win over Poland's Jerzy Janowicz.

Dutchman Igor Sijsling beat German Philipp Kohlschreiber 6-2, 2-6, 6-1 to become the first home player to reach the last four here in more than a decade.
