Overview

• The PGA Tour is conducting a six-week trial allowing distance-measuring devices (DMDs) under strict Rule 4.3, which bans functions beyond distance measurement.
• Davis Riley became the first player penalized under the trial, self-reporting a two-stroke penalty for accidentally activating the slope feature on his rangefinder.
• The penalty temporarily moved Riley outside the projected cut line, but he eagled his final hole to finish 5-under and make the cut.
• Fans and players criticized the rule enforcement, calling for slope-disabled devices and a reassessment of the policy to avoid similar incidents.
• Riley suggested a deeper review of Rule 4.3, emphasizing the need for clearer guidelines as the trial continues into its final weeks.
