Woods was penalized when he moved sticks near his ball behind the first green during the second round at Conway Farms, causing the ball to move. “Oscillation Gate” was set off after a PGA Tour Entertainment employee filmed Tiger in the woods, and it appeared that his ball moved ever-so-slightly. PGA Tour rules official Slugger White declared the evidence was damning enough to slap a one-stroke penalty on Woods (who still disagrees to this day) under Rule 18-2 and another stroke because Woods failed to replace the ball properly.
