The season’s final major is underway at Oak Hill Country Club and the story lines are shaping up as we head into the weekend at the PGA Championship.

Will there be another first time major winner this season? Will we see a player add the Wannamaker Trophy to his existing major championship collection? And will we see another dramatic finish that comes down to the wire?

And as we watch the play unfold, 87 players will be trusting a Pro V1 or Pro V1x golf ball at the PGA Championship. That’s more than three times the nearest competitor with 24 and more than all competitors combined.

Titleist is also the top choice in the iron (41) and sand, lob and approach wedge (142) categories.

Low numbers are being posted and we're rooting for an exciting culmination to the 2013 Major Championship season on the PGA Tour.

Good luck to all of Team Titleist!
