Overview
- Rory McIlroy's driver was deemed non-conforming during routine USGA testing ahead of the PGA Championship, barring its further use at Quail Hollow.
- The PGA of America confirmed that approximately one-third of the field underwent random driver testing, with 8–10 of roughly 30 clubs failing to meet standards due to wear-related 'creep.'
- McIlroy has not addressed the media since the report surfaced, fueling speculation and criticism of the testing process's lack of transparency.
- The PGA of America emphasized that non-conformance typically results from normal wear over thousands of swings, not intentional rule violations, and defended the confidentiality of results to protect players.
- LIV Golf has announced plans to introduce similar driver testing, joining the PGA Tour and DP World Tour in implementing equipment checks without public disclosure of results.
