Federer sets up Djokovic clash

Nadal was troubled by Ferrer8217;s big forehand in the second set. The 2007 Masters Cup finalist broke Nadal twice to lead 3-0, and was then 40-15 up on his serve before Nadal broke back for 3-1. Serving for the set at 5-4, Ferrer led 40-0 but then crumbled, smacking the turf with his racket after his drop shot bounced out and Nadal leveled at 5-5. Nadal won the match when he retrieved Ferrer8217;s drop shot and swiped the ball down the line.

Also Friday, fourth-seeded Nikolay Davydenko beat unseeded Igor Andreev 6-3, 4-6, 7-5 despite losing his serve seven times.
