Simon, Ginepri, Isner go barefoot & shirtless for Muay Thai fun

I've been neglecting other tournaments lately to provide exclusive coverage on the Malaysian Open.

So here's a little bit of updates regarding the PTT Thailand Open.

Gilles Simon, Robby Ginepri and John Isner attended a promotional/traditional event for the tournament yesterday.

They did a Muay Thai (Thai kickboxing) demonstration guided by Thai Olympian Somjit Jongjorhor.

Jo-Wilfried Tsonga did the same thing last year.

I hope the other guys take good care of Simon. He and his 'chicken legs' look too fragile for this sport :P

Here are more pictures at the event.

By the way, if you haven't know yet, Sam Querrey had a freak accident earlier this week while practicing for the Thailand Open.

Querrey was said to have sat on a glass table after practice on Monday and fell through, cutting his right forearm. The injury required immediate emergency surgery.
