In Round 2, Sung Kang could not be stopped at the Shell Houston Open. Round 3 was not nearly as glorious, but Kang did what he had to do to fend off Rickie Fowler.

Kang’s 1-under 71 was good enough to end Saturday with a three-shot lead after briefly losing it to Rickie Fowler. Fowler was brilliant through 16 holes with eight birdies on his way to a 5-under 67 day.

But the 17th and 18th brought him back down to Earth. Fowler bogeyed the 17th and double-bogeyed the 18th, going +3 over the final two holes of the day.

“I drove it well, hit a lot of fairways, hit a lot of greens and made some good putts,” Fowler said. “I’m not looking at the last two holes. It was a great day of golf, and I put myself in a position to win a golf tournament tomorrow.”

Kang meanwhile had four birdies on the day, along with three bogeys. Playing a hole behind Fowler, one of those bogeys came on the 16th when Kang’s five-foot putt unforgivingly lipped out on him.

However, he kept his poise and parred the last two holes for a three-shot lead heading into Sunday’s final round. This is the first time Kang has ever led a PGA event after three rounds in his career.

“I heard a lot of noise in front of us, so I was like, ‘Oh, I know something big is going on up there,'” Kang said of Fowler’s rally.

Kang (-17) and Fowler (-14) will have to contend with Russell Henley who is just four shots off the lead at 13-under.

Luke List who is right behind Henley at 12-under, had himself quite a day with a 7-under 65 performance. Five of his eight birdies came consecutively on holes No. 6 through No. 10.

If Kang wants to punch his ticket to The Masters, he has to hang on to win on Sunday.
