Not defending his Metz title?
Nope, he didn't sign up for it.
Since he plays Davis Cup the week after USO, or probably will just go sit at the bench. So I think the Metz's week is travel week to Asia for Bangkok. I think he meant to defend Bangkok last year but couldn't. He probably is playing this year to make up for it. Well, just my guess, but he seldom commit early to any tournament, but this year he did for Bangkok.
