Federer muses about Nadal return, Tsonga bows out

ROTTERDAM, Netherlands: Roger Federer welcomed the return to tennis of Rafael Nadal, but will not spend much time worrying about his long-time rival's progress as he concentrates on his own game with a Wednesday start at the Rotterdam World Tennis.

While Federer was making his preparations, there was disappointment on court for third seed Jo-Wilfried Tsonga as the French player went down to Igor Sijsling of the Netherlands 7-6 (7/3), 4-6, 6-4.
