I read about this recently and I think its cool that the ATP is doing this for the worker bees of the tour. Top 7 in challenger points qualify and 1 Wildcard from brazil get in with a top prize. Same format as the ATP world tour finals by the looks of it. Chance for a big chunk of change for whoever wins it. Total purse of $220,000..Big dough for the 8 scrubs to fight for!!
