The Fall Series is here for the PGA Tour, and that means it's time to hit the Las Vegas Strip for the Justin Timberlake Shriners Hospitals for Children Open.

In total, 85 players in the 132-player field are trusting Titleist golf balls for their success, more than five times the nearest competitor with 15 and more than all other golf balls combined. Titleist is also first in sand, lob and approach wedges (98) and putters (50).

Defending Champion and Titleist Brand Ambassador Kevin Na is just one of the players who were greeted by Titleist Golf Ball R&D and Leadership Staff with white boxes full of new Pro V1 and Pro V1x prototype golf balls, marking the start of the tour seeding and performance validation process on the PGA Tour. We caught up with the R&D team along with a few players earlier in the week for a closer look at the process - check out the video here.

The first Titleist Pro V1 golf ball debuted 12 years ago at the Invensys Classic in Las Vegas and the eventual champion of the tournament trusted the revolutionary golf ball to find the winners' circle.

Check out the slideshow above for a closer look at some of the action from earlier in the week. Good luck to all the Titleist players this week!
