Pretty sure Del is a free agent. Those pictures are for the balls that Rick Benoit layed out for prominent players. There were pictures for other players that are not on Big B staff, Tony Reyes, Mike Machuga, and Rudy Revs among others.
Del recently resigned his position with Roto Grip, he and Carolyn have opend a pro shop in Watauga, TX called Ballard's Bowling Solutions. Del does not want to travel as much anymore with his beautiful baby girl and all. They do have Roto Grip Staffer Tyler Jensen working for them, he moved down from Colorado! If you are in the DFW area, check out Del, Carolyn and Tyler, they know a thing or three about bowling balls.
