Matsuyama seguito da un colpo dopo il primo round, guidato da uno dopo il secondo e ha avuto un totale di 54 buche di 10 sotto 200 sul par-70, 7,041-cantiere Narashino Country Club corso.
Cameron Trigale, che ha anche sparato 68, trailed by three strokes going to the final hole Saturday but his birdie and Matsuyama’s bogey reduced the lead to just one.
Sebastian Munoz (68), Brendan Steele (70) and Matt Wallace (70), were tied for third, four strokes behind Matsuyama.
British Open champion Collin Morikawa, who shot 67 with a chip-in eagle on 18 and was six strokes behind, said he 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, was shank a shot,” Morikawa said. “si, shanked a pitching wedge straight in the trees.”
“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 really nice to finish on a couple lucky breaks with the tee shot left ending up in the fairway, hitting a bad second shot and then chipping in obviously to end the day.”
Morikawa said it could be an interesting final round.
“We never know. 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,” Morikawa said. “We always feel like we’re always within striking distance and just got to get off to a good start.”
Tokyo Olympic gold medal winner Xander Schauffele shot 68 and was at 2 al di sopra di, 12 strokes behind, as was Rickie Fowler after a 71 Sabato.
The PGA Tour’s only stop on the Asia swing has attracted only three of the top 20 in the world rankings.
