One more shot from ground level.

Titleist Brand Ambassador Matt Jones's new Prototype MB irons were re-gripped and delivered to his locker at Arnonimink.

Scott played 36 holes with his new irons Sunday, and 18 more in Monday's pro-am.

Here's a close-up of Jimmy's new Prototype MB 5-iron.

"The new ones are in the bag," Scott said, " no question about it." (For more reaction from Scott, check out today's Team Titleist Tour Blog post.)

And here's a right-handed set of the new Prototype CB irons being worked on in the Titleist Tour Van.

Can you guess the owner of these new Prototype MB irons?

The custom Cowboy Orange-paintfill and "R" stamping should give it away…

It's Titleist Brand Ambassador Rickie Fowler, of course.

The Titleist Tour Van is a bit more crowded than usual this week, thanks to all the boxes of new Prototype Titleist AP1, AP2, MB and CB irons (712 series).
