Stacy Lewis shot a 7-under 65 on Thursday to take a one-stroke lead during the suspended second round of the Dubai Ladies Masters.
The third-ranked Lewis, a three-time winner this year on the LPGA Tour, had a 9-under 135 total at Emirates Golf Course in the Ladies European Tour's season-ending tournament.
"The putts went in today," Lewis said. "I made a little adjustment on the practice green and it seemed to work. I made a couple of long ones that I probably shouldn't have made and it turned out to be a good day.
"On the longer putts the grip handle was stopping instead of keeping going so I changed that. I think I had 10 or 12 fewer putts and that made the difference. I think I had 24 putts today instead of 33."
Sweden's Pernilla Lindberg was second after a 69. Spain's Carlota Ciganda was 7 under after a 70, and Thailand's Pornanong Phatlum was another stroke back after a 70.
Six players were unable to complete the round because of darkness.
