From the Twitter page of the 2009 U.S. Open champion:
Estoy feliz de poder decirles: VUELVO A JUGAR!!!!!!!!!!!!!!!!!!! Sera en el torneo de BANGKOK el lunes que viene. Muchas Gracias por todo !
I have absolutely no clue what that means, but there are a lot of exclamation points in that Tweet and a fresh, new avatar of a shirtless Del Potro toweling off after a workout, so that's gotta be good, right?
It's been 10 years since I failed Spanish in college, so don't trust my translation of this, but I think that says: "I'm happy to say that I'm returning to play!* The tournament will be in Bangkok on Monday. Thank you very much for everything."
* Followed by diecinueve exclamation points
That's great news. Del Potro hasn't played since the Australian Open because of a wrist injury and will need to get a few events under his belt if he wants to get back to the top of the rankings in 2011.
