A peek inside the Titleist Tour Van, all ready for Tuesday, the busiest day of a major.

Tee party!

Titleist Brand Ambassador Rory McIlroy practices his penmanship.

On to some clubs... Can you guess the owner of these?

Geoff Ogilvy!

No more games. Here's Nick Watney's bag with a 909 and a new Titleist 910 prototype driver that he has been testing out. Don't worry, we'll remind his caddy to keep it to 14 clubs before heading to the course.

A little closer...

And a little closer.

And these belong to Seung-yul Noh.

Welcome, again.
