Nick Price's first PGA Tour win in four years is 18 holes away after he extended his lead to five strokes after three rounds of the Colonial in Fort Worth, Texas.
The Zimbabwean two-time PGA Player of the Year capped a four-under-par 66 with back-to-back birdies to break free from his second-round tie with Mexico's Esteban Toledo.
After the rain-delayed second round was completed, Price birdied the par-four seventh hole and began distancing himself from the field with three more birdies on the back nine.
Back-to-back bogeys at numbers 15 and 16 tightened the leaderboard, but Price got back the strokes with birdies on the final two holes as he reached 10-under 200 and closed in on his first win since the 1998 St Jude Classic.
Price (45) won 15 tournaments in the 1990s, a feat equalled only by Tiger Woods. He had one of the most prolific years in PGA history in 1994 when he recorded six wins, including the British Open and PGA Championship.
Phil Tataurangi, Kenny Perry and Steve Flesch are tied for second at five-under 205 while 52-year-old former champion Tom Watson has a share of fifth place at 206 with Toledo and David Toms.
