The irony is, if Woods encountered this situation a mere five weeks from now, the double hit wouldn't even be a reviewable offense, because the USGA's revised Rules of Golf would be in effect. Rule 14-4. There was also a question of whether or not Woods breached Rule 14-1a, which stipulates that a ball must be "fairly struck" and not "pushed, scraped or spooned." After the review, Woods was cleared of any penalty pertaining to his shot from the bush. Interestingly, Woods admitted after his round that the slow-motion footage of his shot showed that he did indeed strike the ball twice.
No surprise, Tiger is in the scoring tent, reviewing footage from 18. Just saw the slo-mo replay ... and it does not look good.— Tiger Tracker (@GCTigerTracker) November 30, 2018
But because the infraction wasn't discernible by the naked eye, he was spared a penalty. The reason? Decision 34-3/10 (which took effect in April last year) limits the use of video evidence in support of an infraction. In simple terms, if an infraction can't be seen with the naked eye, a player is in the clear, even if video evidence shows otherwise. You can watch a full video of Woods's shot from the bush below.
Tiger admits that, while watching the review, he hit the ball twice. But it wasn't "discernible to the naked eye." So no penalty.— Tiger Tracker (@GCTigerTracker) November 30, 2018
"Did he hit the ball twice?"It's been determined there's no penalty for Tiger Woods on the 18th hole. pic.twitter.com/xMCUAnBkcB — PGA TOUR (@PGATOUR) November 30, 2018
