Titleist Brand Ambassador Rickie Fowler puts in some work on the putting green as Vokey Tour Rep Aaron Dill (left) looks on.

Erik games a trusty Scotty Cameron Tour-only Newport 2 GSS putter.

And now to the face, with a nice touch of custom "E.C." stamping.

Also in Erik's bag: 910D3 8.5º driver, 910F 13.5º fairway metal, 909H 19º & 21º hybrids, CB (4-5) and MB (6-9) irons and Vokey Design Spin Milled 52º and 58º wedges.

If you guessed Jason Dufner, you're correct.

Here's the Titleist bag of last week's Transitions Championship winner, Titleist Brand Ambassador Gary Woodland.

Looks like Gary's got a new 260•08 with some fresh grooves.

Titleist Brand Ambassador Matteo Manassero makes a quick autograph stop.

Here's Matteo's Vokey Design Spin Milled 200 Series 252•08 wedge. He also games a TVD58º.
