Davis Riley dominates at Colonial for maiden solo win as Scheffler falters

Riley, who won the Zurich Classic with Nick Hardy last year, took a four-shot lead into the final round at Colonial and carded a closing 70 to finish 14 under par, five shots clear of Scheffler and Keegan Bradley.

"I knew coming into today it was going to be tough," Riley told CBS after a round containing four birdies and four bogeys.

"Obviously a very tough golf course and when you've got the world number one breathing down your neck it's going to be difficult until the last hole.

"Proud of the way I just stayed in it, fought some adversity early, just kind of hung in there and played some really good golf coming down the stretch and just super excited and proud of myself."

Seeking a fifth win of the season, Scheffler was three over par for his first 10 holes before making birdies on the 13th and 17th in a final round of 71.

It was a sad day at the PGA Tour event, however, after Grayson Murray's parents, Eric and Terry Murray, confirmed that their son had taken his own life.

News broke that Murray had passed away, age 30, the day before.

Murray's parents asked golfers to wear ribbon pins in black and red to honor Murray, who wore the colors of his hometown NHL team, the Carolina Hurricanes, when competing on Sundays.

"Obviously super-sad day in the golf world," Riley said. "My heart just goes to him and his family and there was definitely a little extra to play for today."
