"I had a few struggles with my drives but, I can't play good every single round," Ko said. "Third in a professional event is a pretty good result and I can't say I'm not fully pleased."
Meanwhile, Tseng shot the best round of the last day - a 7-under 66 - to dash past Ko into second place, two shots behind Shin.
"I was always feeling good here and I tried my best today," Tseng said. "I got some pretty good lucky bounces, too. I didn't drive as well as the last few days, but I got some good bounces, some good kicks on the fairway, hit a tree, bounced on the fairway so it's kind of really lucky."
