Sorry for the delayed update. After being awake for almost 40 hours straight, I had to sleep Monday away.
They quit at 4:00am w/ BJ up 3 games (to 7) in the 10-ball set. They'll be resuming tonight around 6:00pm.
At one point Sparky was up 5 and BJ ran it back to even. At that point we doubled the bet.
After that, BJ got to the hill a number of times, and each time he broke for the set-winning game he scratched and Sparky either made a fantastic 1-10 combo or just ran out.
These guys play some of the best pool I've ever seen in person.
