Report -- Rory McIlroy driver deemed nonconforming ahead of PGA - ESPN

CHARLOTTE, N.C. — Rory McIlroy was forced to use a backup driver in the PGA Championship when his regular driver was tested and deemed to be nonconforming after he arrived at Quail Hollow, according to a report on SiriusXM PGA Tour Radio on Friday.

McIlroy was tied for last in driving accuracy among the 74 players who made the cut Friday, hitting only 10 fairways in two rounds. On Thursday, he hit just 4 of 14 fairways, tied for 150th among the 156 players in the field.

The Masters champion made the cut on the number after a bogey on the final hole when he drove left beyond a creek against corporate tents.

For the second straight day, McIlroy left Quail Hollow and declined to speak to the media.

«That program is consistent with the same level of support that we provide to the PGA Tour as part of their regular program for driver testing,» the USGA said.

Results are confidential.

The PGA of America did not immediately respond to a request for information, such as how many players submitted drivers for testing, instead referring to the USGA statement.

The tests are typically random, and it is not unusual for testing ahead of major championships.

One such case was in 2019 at Royal Portrush for the British Open, when Xander Schauffele was among 30 players randomly selected to have his driver tested by the R&A, which governs golf everywhere but the U.S. and Mexico.

Schauffele said he wasn't aware his driver didn't conform until notified, and then worked into Tuesday evening that week to
