The PGA Tour confirmed neither Patrick Reed nor Rory McIlroy broke any rule during the Farmers Insurance Open.
Both players received a drop after arguing they were unable to properly hit their balls as they originally sat. In Reed's case, he picked up the ball before calling for a rules official.
"John Mutch, Ken Tackett and Gary Young have reviewed the Rory McIlroy videos from No. 18 yesterday and determined that it was virtually the same situation that Patrick Reed faced on No. 10 during the third round," the PGA Tour said.
"It was reasonable for both players to conclude—based on the fact that they did not see the ball land, but given the lie of the ball in soft course conditions—that they proceed as the Rule allows for a potential embedded ball.
