The PGA Tour has returned to Las Vegas, the city famous for all its bells and whistles. On the range this week at TPC Summerlin, however, it's a delivery of plain white golf ball boxes that will have all our Titleist tour pros talking.

Care to guess what's inside?

Still thinking?

Enough of the build up, we’ll let you in on the scoop: This week marks the beginning of the tour seeding and performance validation process for the new Pro V1 and Pro V1x prototype golf balls on the worldwide professional tours.

After months of extensive player testing, Fordie Pitts and Jeff Beyers from the Titleist Golf Ball R&D team will be on site, with white boxes under their arms, ready to help players continue the testing and fitting process.

It's an exciting time at Titleist, as performance validation from the best players in the world is one of the final checkpoints along the way to launching a new product in the market.

Fast Fact: It was around this time 12 years ago that the first Titleist Pro V1 golf ball debuted in Las Vegas. Since then, nearly 235,000 players have teed up Pro V1 and Pro V1x golf balls in competition across the worldwide professional tours, as compared to just under 45,000 for the nearest competitor.

Stay tuned to Team Titleist as we will continue to provide you with more details and inside-the-ropes updates as the tour seeding and performance validation process continues.
