CHIBA, Japan -- Japanese golfer Hiroshi Iwata shot a 7-under 63 Thursday to take the first-round lead at the PGA Tour's Zozo Championship.
Iwata had a one-stroke lead over Joaquin Niemann and 2021 Masters champion Hideki Matsuyama on the par-70, 7,041-yard Narashino Country Club course.
Defending champion Patrick Cantlay is taking the rest of the year off and is not playing in what has turned out to be the only PGA tournament on the Asia swing. Only three of the top 20 in the world are playing in Chiba.
Tokyo Olympics gold medal winner Xander Schauffele shot 70, as did Rickie Fowler, who is playing on a sponsor's exemption for the second straight year.
Mackenzie Hughes of Dundas, Ont., also shot a 70 while Roger Sloan of Merritt, B.C., shot a 2-over 72.
British Open champion Collin Morikawa shot 71.
Tiger Woods won his 82nd career PGA Tour title at Narashino in 2019.
