Hideki Matsuyama will be looking for more of the same on Sunday as he aims to seal the biggest win of his career to date at the WGC-HSBC Champions.
Matsuyama maintained his three-shot lead over defending champion Russell Knox with a bogey-free 68 at Sheshan International Golf Club on Saturday.
Having mixed 19 birdies with six bogeys over the first two days, the Japanese avoided any dropped shots in an assured third-round performance.
"The first two days, making lots of birdies, it's a lot of fun," Matsuyama was quoted as saying by the European Tour website.
"But today, when you're in a position to win, playing smart and making no bogeys was very satisfying to me."
Looking ahead to the final day, the world number 10 added: "Everyone is so good. I know I'm going to have to make some birdies.
"But I think the key for tomorrow's round will be not making any bogeys."
Knox matched Matsuyama's 68 on Saturday and remained upbeat over his hopes of retaining the title he claimed 12 months ago.
"I'm thrilled to be in this position," said the Scot. "I'm not going to give up my title without a big fight.
"The way Hideki played today, he's probably going to play similar tomorrow. I'm going to have to be foot down, be aggressive and try and catch him."
