Canadian Women's Open leader Candie Kung believes her recent good form is largely thanks to her improved putting.
The 34-year-old from Taiwan moved into a two-shot lead in Vancouver after carding a bogey-free eight-under-par 64 on Friday, ahead of Lydia Ko and Karine Icher.
Kung is seeking her first victory on the LPGA Tour in nearly seven years, having finished in a tie for second place at the Portland Classic last week.
"I just went out there, played one shot at a time, and I knew that I was putting pretty good," the halfway leader Kung said.
"I missed a few out there from about ten feet. I was hitting them pretty close all day. And then made some key putts coming in."
The Taiwan-born golfer shot up the world rankings in 2003 when she won three tournaments, but since then her only victory on the LPGA Tour came in South Korea in 2008.
She finished outside the top 30 in each of the majors this year and her last credible performance at golf's blue riband events came at the 2009 US Women's Open, where she finished as the runner-up behind Eun-Hee Ji.
Even though she finished eight shots behind eventual winner Brooke Henderson last week, Kung said that the second-placed finish gave her renewed confidence for this week's tournament.
"I've been playing well," Kung said. "Just the putter has to go and so far it's been going pretty good the last six tournament days."
