KAPALUA, Hawaii – Bryson DeChambeau’s decision to putt with the flagstick in the hole this week has drawn plenty of attention, particularly with the 25-year-old leading the field at the Sentry Tournament of Champions in strokes gained: putting through two rounds.
In November, DeChambeau explained that his decision to putt with the flag in depended on the flagstick’s coefficient of restitution (COR) and noted that the USGA uses different kinds of flagsticks for the U.S. Open that he likely will not keep in.
The Rules of Golf stipulate a flagstick must be .75 inch in diameter and the USGA recommends it be at least 7 feet in length.
