World number four Cameron Young stumbled early but rallied to stretch his lead to six strokes after Saturday's third round of the PGA Cadillac Championship.

The 28-year-old American followed an opening bogey with four birdies and a bogey to fire a two-under par 70 and stand on 15-under 201 after 54 holes on the Blue Monster course at Trump National Doral in Florida.

"It was a little bit difficult to find a rhythm, just the wind and the direction it blew was really tricky," Young said. "Every hole was a substantial cross wind."

"It's really just a matter of trying to manage that and give yourself as many opportunities as you can."

World number one Scottie Scheffler fired a 69 to seize a share of second place on 207 with South Korean Kim Si-woo and Norway's Kristoffer Reitan.

Americans Ben Griffin and Matt McCarty shared fifth on 208 with Canada's Nick Taylor.

Stormy forecasts for Sunday afternoon have prompted organizers to have players make morning starts in the final round in threesomes off the first and 10th tees.

"Today was kind of a good test run of how tomorrow will be," Young said. "I'm sure it will not be as easy as I want it to be. Sounds like the weather's not going to be great.

"It'll be a fight from the beginning and just looking to execute the way that I did for the most part today -- just keep it in front of me and try to make some putts."

Young, who turns 29 on Thursday, won the Players Championship in March and shared third last month at the Masters.

After starting the day with a five-stroke lead, Young found water with his second shot on the way to a bogey at the par-five first hole while Taylor sank a six-foot birdie putt to close within three.

"It wasn't my best shot," Young said of his dampened shot. "With a good bounce it's not in the water. With an average bounce it's kind of close. I happened to get a bad one. I can't be mad for hitting driver, 6-iron at the middle of the green on one.
