That's where he keeps part of his skull.
It's a not-so-subtle reminder of the long, remarkable journey Holmes has endured — one that included recovery from two brain surgeries and culminated Sunday with a one-shot victory over Jim Furyk in the Wells Fargo Championship.
Holmes shot a 1-under 71 to finish at 14-under 274 and take home the $1.24 million prize — the largest single paycheck of his career.
It's Holmes' first victory since he had two brain surgeries in 2011, as well as operations for a broken ankle and an issue with tennis elbow.
Holmes was diagnosed with structural defects in the cerebellum known as Chiara malformations, and he had twice had surgery to fix the problem. The first was to remove a piece of his skull that was pressing on his spinal cord and another was due to an allergic reaction to the adhesive on the titanium plate at the base of his skull.
"It was causing me to be dizzy and vertigo-like symptoms and really bad headaches," Holmes said.
Through it all, Holmes never doubted he'd return to the PGA Tour and find success.
"I never let myself go there," Holmes said.
Holmes' two other wins came at the Phoenix Open, in 2006 and 2008.
