Colombia's Villegas voted PGA Player Advisory Council chairman
The 42-year-old South American star will serve as chairman for the remainder of the year then replace Jordan Spieth as member of the PGA Tour Policy Board for a three-year term starting in 2025.
Voting concluded on Tuesday between Villegas and American Kevin Streelman for the job of directing a council that consults and advises PGA commissioner Jay Monahan and the policy board on issues impacting the tour.
The PGA Tour Policy Board is in talks with the Saudi Arabian Public Investment Fund, backers of the rival LIV Golf League, about making a final deal from a framework agreement reached last June with Monahan.
Other players on the current board, all of whom have terms through at least 2025, include Tiger Woods, Adam Scott, Patrick Cantlay, Peter Malnati and Webb Simpson.
Villegas was a PGA Tour rookie in 2006 and in 2008 won the Tour Championship and BMW Championship. His most recent tour title, and first in more than nine years, came last November in Bermuda, securing his tour status through 2025.
