Early Monday morning at The Barclays, long before any players had arrived for the start of the FedEx Cup Playoffs, the only sounds heard in the locker room at at Plainfield (N.J.) Country Club were from the opening and closing of lockers.

It was delivery time for the new Prototype Titleist Vokey Design SM4 wedges, signaling the official start of the seeding and tour validation process critical to the development of all Titleist golf equipment.

"It was a great surprise today when I opened the locker and I saw three new wedges in there," said Titleist Brand Ambassador Robert Karlsson.

Later in the day, Karlsson spent about 45 minutes on the range with Master Craftsman Bob Vokey, testing the new Prototype SM4 wedges and giving Bob feedback on the new SM4 groove technology with three additional scoring lines.

Titleist Brand Ambassador Scott Stallings hadn't planned on going to the course Monday until he found out what was waiting for him in his locker.

"I wanted to try out the new wedges," Scott said. "I couldn't wait."
