Phil Mickelson loses two holes due to rules mistake at Presidents Cup

During the 2015 Presidents Cup in South Korea, Phil Mickelson lost two holes after mistakenly playing the wrong ball. This incident occurred in a match where Mickelson and Zach Johnson faced off against Jason Day and Adam Scott. Midway through the match, Mickelson switched his ball model, unaware it breached match rules. The rules committee's decision to disqualify Mickelson from the hole compounded the issue, leaving Johnson to play without support. The committee later acknowledged their error, stating Mickelson should have been permitted to continue playing the hole. Team USA ultimately secured a half point, but the mishap likely cost them a full point in the match's outcome.
