D.H. Lee went from looking for birdies to flipping the bird Saturday at the PGA Tour's AT&T National in Bethesda, Md.
After firing long with his approach shot on the 12th hole at Congressional, the 26-year-old South Korean, apparently reacting to a fan in the gallery, flashed his middle finger toward the crowd.
The gesture was caught by CBS' cameras and later replayed during the telecast.
Lee had a bogey on the hole, one of several missteps throughout his third round.
He began the day in a tie for fourth, two shots off the lead, and made the turn at even-par 36. But things quickly unraveled on the back nine, as Lee took a double-bogey 5 on the 10th hole, the bogey on the 12th and bogeys on Nos. 15 and 18.
