BELMONT, Mich. — Inbee Park found a new putter — and her old touch.
The South Korean took the second-round lead Friday in the Meijer LPGA Classic, birdieing her first three holes en route to her second straight 5-under 66.
The third-ranked Park finished on the front nine, adding birdies on the par-5 fifth and eighth holes in her bogey-free round. She won six times last year in rising to No. 1.
"My putting feels like I'm back to last year," Park said. "Hopefully, I can hole some more putts the next two days."
After using a mallet putter since 2008, Park tried a friend's blade putter Tuesday and started making putts. She hit 27 putts in each round after having TaylorMade quickly make her an identical version.
No. 4 Suzann Pettersen was a stroke back at 9-under 133 after matching the course record with 64. Women's British Open winner Mo Martin withdrew with a thumb injury.
