MEMPHIS, Tenn. — Hideki Matsuyama felt his lower back starting to act up. On a whim, he decided to put a new putter in his bag for the start of the PGA Tour postseason. And now the Japanese star has a five-shot lead going into the final round of the FedEx St. Jude Championship.
''I am surprised,'' Matsuyama said through his interpreter, breaking into a big smile when he added, ''but I did play well today.''
He played well enough for a second straight 6-under 64 that enabled him to pull away from a crowded field and put plenty of distance between him and Nick Dunlap.
Matsuyama quickly atoned for an early bogey by drilling a 3-wood over the water to 15 feet and making the eagle putt. He kept adding birdies the rest of the day in more steamy weather and no one could stay with him.
Denny McCarthy, who was tied for the 36-hole lead with Matsuyama, put four bogeys on his card before registering his first birdie. Sam Burns had only five pars — and a broken driver — in his round of 70 to fall back. Scottie Scheffler lost ground with a few suspect chips and was seven shots behind after a 69.
''I felt like I got away with some stuff, so hopefully clean it up a little bit and give myself a lot more opportunities,'' Scheffler said.
Scheffler was at 10-under 200 along with Burns, who slammed his driver to the ground on No. 9 and the head broke off. He made double bogey to go with five bogeys and seven birdies. It was quite a day.
Dunlap did his best to stay close and was within three shots until one wild drive too many. He went so far right on the 12th that he cleared the water and landed on the other side, and then managed to save par. But he hit right again on the 13th in deep grass, couldn't reach the green and took bogey.
