Second seed Jo-Wilfried Tsonga crushed close friend Gael Monfils with a 6-3 7-6 victory in a first-round French rendezvous at the Japan Open on Monday.
Tsonga and Monfils live close to each other in Switzerland and often socialise together, but the French connection counted for little once they stepped on court as Tsonga overpowered his compatriot with a brutal display of hitting.
The world No.8, still feeling his way back from a knee injury, bulldozed his way to a 3-0 lead before taking the first set with a vicious serve which was too hot for Monfils to handle.
“It’s always difficult to play a friend,” Tsonga told reporters. “I’ve known Gael such a long time.
“We hang out, we play video games, go out for dinner. So it wasn’t fun. But on court you give 100 per cent out of respect for your friend.”
Monfils, brightening up centre court with his brilliant orange attire, began badly off-key but made more of a fist of the second set, forcing a tiebreak.
However, Tsonga, the 2009 Japan Open champion, simply had too much firepower and a fourth win in five meetings was never in serious doubt.
