In this week's episode of 'Under the Strap,' host T.J. Auclair is joined by caddies Scott Sajtinac (Jason Dufner), John Wood (Matt Kuchar) and Heath Holt (Greg Chalmers) to learn about how the Association of Professional Tour Caddies (APTC) works and how it benefits its members. Sajtinac is the president of the APTC, Wood is vice president and Holt is the treasurer. Along with learning about the group -- comprised of nearly 200 PGA Tour caddies -- the guys also announce the APTC's new benevolent fund, set up to help caddies through difficult times... something that got off the ground thanks to a generous donation from a top Tour player.
