Sam Burns lit up the course on Friday, shooting a 62. He couldn't match that scorching pace on Saturday, though he did enough to remain atop the leaderboard at the AT&T Byron Nelson in McKinney, Texas.
Burns shot a 3-under 69 in the third round to move to 20 under, just one stroke ahead of K.H. Lee and three strokes ahead of Jordan Spieth, Charl Schwartzel, Matt Kuchar and Alex Noren.
That sets up what should be a tight, compelling final round on Sunday.
