Hideki Matsuyama of Japan took advantage of the par 5s for a 4-under 68 and kept his three-shot lead in the HSBC Champions on Saturday.
Matsuyama played bogey-free at Sheshan International for the first time all week. He didn't produce as many birdies, picking up three of them on the par 5s. A two-putt birdie on the par-5 18th was enough for him to maintain his margin.
He was at 17-under 199.
Defending champion Russell Knox never got closer than two shots on another chilly day. He also had a 68 and was at 14-under 202.
Daniel Berger ran off four straight birdies late in his round to get in the mix, and he saved par from the water on the 18th for a 67. He was four behind.
