Lucas Glover removes shoes at 3M Open after spike‑mark complaints

During the final round of the 3M Open on July 26 2026 at TPC Twin Cities, former U.S. Open champion Lucas Glover sank a 10‑foot birdie putt on the 10th green, then walked off the green and removed both shoes before retrieving his ball. Broad broadcast speculation suggested the act was a protest against the AimPoint green‑reading technique, a method Glover has publicly criticized. Within hours, the PGA Tour and Glover clarified the real reason. Glover posted on Instagram, "No, not even close. Nothing to do with AimPoint, actually," and explained he had been approached about complaints that his metal spikes were marking the soft, damp greens. He said a rules official warned him after a competitor in the following group complained, and he removed his shoes in a light‑hearted response. The golfer finished tied for 57th after rounds of 65, 70, 72 and 72. The incident sparked discussion of spike‑mark rules and the AimPoint debate but had no impact on the tournament outcome.
