Mark Wilson took to Twitter to break the news: he was disqualifying himself.

Wilson, a 44-year-old pro with five career PGA Tour wins, had to bow out of this week’s Barracuda Championship (opposite of the WGC-FedEx St. Jude Invitational) when he realized his greens-reading book was non-conforming, a violation of Rule 4.3.

Wilson said he grabbed his 2014 greens book and since it fit in his yardage book, he assumed the scaling limits would be fine. They weren’t. The revised Rules of Golf state greens books must scale three-eighths of an inch to 5 yards.

Wilson was tied for 51st after three rounds before the DQ.
