Looks like Jo-Wilfried Tsonga is back in action.

The 23-year-old from Le Mans, France advanced at the U.S. Open following a first-round win against Santiago Ventura, needing four sets for the win, 6-7, 6-4, 6-2, 6-3.

Tsonga stunned the tennis world (and Rafael Nadal in the semis) at the Australian Open with an unstoppable aggressiveness and uncanny ability to make impossible shots.

While not quite recovered from recent knee surgery for an Olympic appearance, Tsonga makes his official return to tennis. He missed the majority of the clay and grass seasons due to the operation and wasn't able to return to the practice courts until the beginning of August.

Tsonga withdrew from Monte-Carlo in May due to the recurring knee injury, which stems from either his hard work on the courts or his hard play in the clubs.
