Min Woo Lee rudely crashed what was supposed to be Scottie Scheffler’s H-town coronation, roaring from one-stroke back through two rounds to open a five-stroke lead over the world’s No. 1-ranked golfer Saturday, setting himself up to win the Texas Children’s Houston Open for his first championship in his rookie season on the PGA Tour.

The Australian chipped in for birdie to take the lead, en route to a 7-under 63 as he closes in on his first PGA Tour victory.
