Hi, sometimes I've noticed in pro tournaments that when they are using the Sardo rack, the players will rack the balls by hand instead of using the Sardo. By hand I mean they don't even use a triangle, they just place the balls there one by one in the 9-ball diamond formation. I noticed people doing this on a few different matches during the UPA event. The Sardo rack was sitting right next to them, but they werent using it. Does anyone know why? All the other tables around them were using the Sardo rack, but these guys werent. Two other players did the same thing later on that night.
