It looks like Clay Warrior is not going to shut down his season quite yet General.
The word is that he will honor the last year of his 3 year contract with Swiss Indoors ATP 500 at Basel and play next week.
Note that Rafa has also signed up for doubles with 40 year old Serbian Nenad Zimonjic.
Now predict if he will go farther in the singles or the doubles.
Maybe we need to see the draw first (available on Saturday around 4 pm Swiss Time)?
If he shuts things down after Basel, that will give him all of November and December to get more fit and practice on clay.
But my guess is that instead, he'll practice on the indoor hard court he built and seems infatuated with.

Respectfully,
