In a shocking turn of events at the 2025 PGA Championship at Quail Hollow Club, the PGA of America has officially announced the disqualification of Rory McIlroy following a ruling by the United States Golf Association (USGA). The decision, confirmed on May 18, 2025, stems from the use of a non-conforming TaylorMade Qi10 driver, which the USGA determined provided an illegal advantage, violating the Rules of Golf.

The controversy began earlier in the week when McIlroy’s driver was flagged during a routine equipment check on Tuesday. Initial reports suggested the issue was related to “CT creep”—a common occurrence where a driver’s face becomes more flexible over time, exceeding the USGA’s limit for spring-like effect. McIlroy was reportedly forced to switch to a backup driver before the first round, and he struggled off the tee, hitting only 10 fairways over the first two rounds. Despite this, he managed a 1-over-par total after 54 holes, placing him at T61 heading into the final round.

However, further investigation by the USGA revealed that McIlroy had continued to use the non-conforming driver during practice sessions after the initial ruling, an action deemed as intentional non-compliance. The Rules of Golf (Rule 4.1) are clear: using equipment known to be non-conforming, even in practice rounds during a tournament week, can lead to disqualification if it’s determined the player sought to gain an advantage. The USGA’s statement highlighted that McIlroy’s actions compromised the integrity of the competition, leaving the PGA no choice but to disqualify him.

McIlroy, who had just completed the career Grand Slam with a Masters win last month, has not yet commented on the ruling. His performance at Quail Hollow had already been under scrutiny, with fans and analysts noting his uncharacteristic struggles off the tee. The disqualification marks a stunning fall for the Northern Irishman, who was seen as a favorite to contend for a third PGA Championship title at a venue where he has historically excelled.

The golf community is reeling from the news. Scottie Scheffler, currently leading at -11, expressed sympathy but emphasized the importance of fair play. Meanwhile, social media has erupted with mixed reactions—some fans label McIlroy a “cheater,” while others argue the penalty is overly harsh for what could be an oversight. As the final round continues, the focus now shifts to Scheffler, Alex Noren (-8), and a chasing pack that includes Jon Rahm and Bryson DeChambeau, all vying for the Wanamaker Trophy in McIlroy’s absence.

This incident raises broader questions about equipment testing protocols and the pressures on top players to maintain an edge. For now, McIlroy’s legacy takes a significant hit, and his path forward remains uncertain as the golf world processes this unprecedented scandal.
