Sam Burns leads AT&T Byron Nelson with sights on second TOUR win Sam Burns interview after Round 3 of AT&T Byron Nelson MCKINNEY, Texas — The last group of the AT&T Byron Nelson includes a player with no wins on the PGA TOUR and a player who just got his first. The tee time Sunday for Sam Burns and K.H. Lee was moved to 10 a.m. to avoid the rain expected later in North Texas. That means Burns and Lee have even less time to ponder their circumstances, which for Lee means his first TOUR win and a berth next week in the PGA Championship.
