Masters champion Hideki Matsuyama has held on to a one-stroke lead at the US PGA Tour's Zozo Championship after a two-under 68 on Saturday which included a bogey on his last hole to make things interesting heading into the final round.

Japan's Matsuyama trailed by one shot after the first round, led by one after the second and had a 54-hole total of 10-under 200 on the par-70, 7,041-yard Narashino Country Club course.

American Cameron Tringale, who also shot 68, trailed by three strokes going to the final hole but his birdie and Matsuyama's bogey reduced the lead to just one.

Colombian Sebastian Munoz (68), Brendan Steele (70) of the United States and Englishman Matt Wallace (70), were tied for third, four strokes behind Matsuyama.

The only Australian in the field, Matt Jones, bogeyed the final three holes and is tied for 19th after a three-over (73) left him one-under the card.

Collin Morikawa, who shot 67 with a chip-in eagle on 18 and was six strokes behind Matsuyama. The British Open champion added a new shot to his repertoire on the par-5 sixth hole but it's not one that he wants to repeat.

"I did something in my career that I haven't done yet ... shanked a pitching wedge straight in the trees," Morikawa said.

"It was kind of a grind. I really had no clue where the ball was going to go, I was kind of just trying to make contact and thankfully the putter was working today.

"Obviously I'm going to have to go make birdies tomorrow, Hideki's obviously not going to make a bunch of bogeys, but we'll see where the day ends."

Tokyo Olympic gold medal winner Xander Schauffele shot 68 and was at two over, 12 strokes behind, as was compatriot Rickie Fowler after a 71.

The PGA Tour's only stop on the Asia swing has attracted only three of the world's top-20.
