LOUISVILLE, Ky. — A look back at the trending topics in golf the last time the PGA Championship was held at Valhalla in 2014:
Dustin Johnson was No. 16 in the world and No. 5 in the Ryder Cup standings when he announced he was taking a leave of absence to seek professional help for personal challenges. He asked for privacy “as I embark upon this mission of self-improvement.” Golf.com reported he had failed three drug tests and was suspended. The PGA Tour said he had not been suspended. He didn’t play again for six months.
