Roger Federer had to fight hard for his spot in the ABN Amro final in Rotterdam. The former world no.1 defeated the Russian Nikolay Davydenko 4-6 6-3 6-4 and will play Juan Martin del Potro for the title.
Davydenko, who has been struggling recently, made a very impressive start, taking the first set 6-4. He was a break up in the second set, but the Swiss broke back and managed to controll the set from then onwards and levelled the match at 1 set all.
The third set went with serve all the way to 4-3 for Davydenko, when he had three break point chances on Federer´s serve. But the 16 time Grand Slam champion saved all of them and that gave him a boost. After holding his serve, he broke Davydenko just before serving out the match.
In the other semifinal, Juan Martin del Potro from Argentina only needed two sets to book his place in the final. He dismissed the Czech Tomas Berdych 6-3 6-1.
This is Del Potro´s first Rotterdam appearance and he seems to be on top form going into Sunday´s final.
The last match played between the two final contenders was at this year´s Australian Open quarterfinals, where Federer prevailed in straigh sets 6-4 6-3 6-2.
