Tokyo: Former champion Jo-Wilfried Tsonga crashed out of the Japan Open in the second round on Wednesday, ambushed 6-4, 7-6 by Croatia's Ivan Dodig in the tournament's first major upset.
Top seed Juan Martin del Potro thrashed fellow Argentine Carlos Berlocq 6-2, 6-2 to reach the quarter-finals of the $1.43 million event in Tokyo before Tsonga, still feeling his way back from a knee injury, was unceremoniously bundled out.
"I'm not shocked by this result," the second-seeded Frenchman told reporters. "This game is difficult enough with two legs. With one and a half it's complicated."
