(CNN) -- World number one Rafael Nadal again showed his amazing battling qualities as he held off Frenchman Jo-Wilfried Tsonga in three tough sets to reach the semifinals of the Rotterdam men's Open.
The top-seeded Spaniard had been taken to three sets in both of his previous matches this week, and Friday proved no different as he beat seventh seed Tsonga 6-4 6-7 6-4.
The Australian Open champion had chances in the second set to wrap up a quick victory, but could not convert as Tsonga won six successive points in the tie-break to take the match to a third set.
Meanwhile, second seed Andy Murray is also through to the last four after his French opponent Marc Gicquel was forced to pull out of their quarterfinal clash with a hamstring injury.
Despite the injury, Gicquel still managed to take the second set off the Briton before eventually retiring with the scoreline at 7-6 4-6 3-0.
Murray will next meet Croatia's Mario Ancic, who put out 2007 champion Mikhail Youzhny 6-4 6-2. Ancic, ranked 28th, has lifted two of his three career titles in the Netherlands and was a Rotterdam semifinalist four years ago against former world No.1 Roger Federer.
