Nick Faldo said recent testing showed a one-inch tee flew 25 yards shorter than the optimal 2¼-inch tee, with less ball speed and carry. McIlroy said he would support testing the idea with professionals.
The comments came as golf's distance debate continues, with the planned golf ball rollback pushed from 2028 to 2030. McIlroy said distance control could involve tees, balls and other equipment factors.
