SAN DIEGO — When it comes to short game, many of the game's premier players show a lot of creativity. But Rocco Mediate, who started the third round of the 108th U.S. Open tied with Robert Karlsson and Tiger Woods in second place, takes it to a whole new level.

Mediate stamps and colors the back of his Callaway X Forged wedges himself. All of the Xs and shapes that you see on the back of his wedges were made by hammering a metal stamp directly into the steel, then filling in the area with paint.

"I'm nuts, I'm a little bit of a lost soul," he told me after his press conference Friday afternoon.
