beating the ghost in 9 Ball and 10 Ball - definitely good enough pocketing, position play and concentration ability to run 50+ in straight pool regularly9 ball ghost. 7-3……win??
edit: and it's a tough GC III with an old cloth you have there. Your 51 balls run would easily be as difficult as 70+ on an easy table like the one, where Jayson ran 714 on.
